I find myself in the early and mid game using Fear quite a bit. At what level should I stop using Fear and use Phantasmal Killer at 4th level instead (I'm talking about vs Bosses, vs non-bosses I just use Fear 3)? Although Phantasmal Killer doesn't even make much sense when you can cast 6th and 7th level spells as the damage is pretty low. What to do?

The main benefits of both are the Frightened Condition, both a powerful and fleeting effect, which both spells do on roughly the same level against a single target.
Given the main advantage to it is the Frightened Condition, I may just leave it has a LV4 spell, if at all, at least in terms of bosses {which I will be assuming are going to be a bit higher level then you.} The damage is nice, but heightened versions do not improve the damage on a save, {assume the boss will be a bit more likely to make the save} In addition, while there is always a chance the spell could kill a boss outright, the incapacitation part of it makes that outcome extremely unlikely. While the extra damage can be helpful if they make the Fort save against the Crit effect, the main thing is the Frighted 4 Condition {which can be devastating to say the least} and your party is going to have a free round while it is running away, effects which do not improve upon casting casting it at a higher level. {ie, you and your party should be able to kill it pretty easy at that point, with or without higher damage.}
If talking about bosses only, LV4 would most likely be where I would leave it, with a LV3 Fear being able to achieve most of the desired results at a lower spell slot. Phantasmal Killer does have the advantage of range however, which is also something to considered.

One of the nice things about this edition is that low level spells have the same DC as your high level spells. But I'm sure everyone already knows that.
The two spells are actually rather similar. Especially for battling bosses that are likely to at least not crit fail the save and may ignore incapacitation effects.
So ignoring the crit fail instakill effect of phantasmal killer, the main difference is that phantasmal killer also does some damage.
So it is definitely an upgrade, but may not even be a needed one. Depends on how much you want to be able to do damage while also causing the fear effect.

Ya I mean it seems as though Fear (1st level) is just as good early game as it is even into the late game although it may look a bit silly casting a 1st level spell vs a 17th level Dragon. I mean sure you have spells like Mask of Terror, but I would rather save that high level spell slot for something better.

PF2 is a game where you can not ignore your lower level slots/spells, both because you do not have has many of them to work with as you did in PF1, and because they can {partly because of what breithauptclan said about DC's, and because there are some really good lower level spells] put in some work.

Unlike PF1, spells of all levels remain as effective as an other (in terms of DC), what defines higher levels spells versus lower level spells is that they should theoretically do more than lower level counterparts.
They usually do.
But against on level and higher level enemies you wont get a crit fail, and often those better effects are mostly on the crit fail side.
So many times a low level slot can be as effective as higher level spell slots.

As long as you're not blasting or summoning, this is almost always true!

That's a good caveat, yeah blast spells damage is pretty spell slot dependent and what you can summon is also slot dependent.
Though, summons in this edition are much weaker and more about having versatile options available for countering certain kinds of conditions or about soaking a hit or two. Summons just don't have a lot of staying power if the enemy focuses on them, but they're not supposed to either.
In PF1, you could end up in a situation where a summon might be 75% as effective as a melee character, but you spent a single spell slot on it and the other player dedicated their whole character. You still had all your other slots and class features. It made some melee character players really feel inadequate because they could be (mostly) replicated with a single spell slot.

Blast spells, summoning spells, healing spells, counteracting spells, buff spells, incapacitation spells, multi target debuff spells. In fact, all spells but utility spells and single target debuff spells need your higher spell slots to be effective.
In PF1, you could do a lot with your low level slots. In PF2, they are mostly for utility spells.

No, see I strongly disagree Bidi. The healing spells, buff spells, and multi target debuffs all do fine. They just don't do as much as their higher level counterparts.
Though you can probably find a better way to use a low level spell slot than for a weak heal, it's not really diminished if you just need to heal a little.
The fact that higher level spells are better is obvious, they should be. But low level spells aren't weaker in PF2 like they were in PF1 (they basically never worked if they involved a save) and were relegated to buff and utility only.
In PF2 your 1st debuff spell will work just fine, it just wont do as much as your 5th level debuff.

Buff spells are some of the most consistent across all levels, tbh (with some exceptions, cough magic weapon cough). Take a spell like Blur; rock solid as it gives a 20% miss chance on any spell or attack - amazing. 15 levels later and it’s still doing exactly that.
Even something like Heroism doesn’t need to be heightened to be relevant. A +1 is a +1, and can be a great thing to burn one of your lower level spells on.
