Really depends: I think the core of the issue is that it allows for low-mid level characters to be MORE powerful, while Med-High become WEAKER. Depending on the type of game you like (low or high) and the power level you feel it should be will be the basis of your opinion. Personally I like the options, but would prefer if there was some kind of "relationship" between the classes
I love the ability of multiclassing as that allows the character to grow organically. Archetypes are best for when you pre-plan your character's entire advancing.
While I like cherry picking, I won't cherry pick if the class does not fit my idea of the character. I build for flavor, not raw power. I like power, but it is not the only thing I build for,

I'm sure this will be a pro-multiclass thread... so I will be in early to say I don't like it that much. Mainly because it is just used for (in my experience) cheese super builds and one trick ponies. It's fine if that's what you like, but it seems too much like playing a video game, where personal power is more (sometimes much more) important than the story.
I used to be into power builds and multiclass cherry picking when I was younger. However, I find I like the story and the characters backstory now more than the combat. Finding out who done it, rather than which one of us killed it is much more enjoyable. I like the team-endeavor idea, where each person is a specialist and expert in their field. When everyone is good at massive damage and can do magic, open locks, what have you... just less interesting to me.
I personally dislike the way of multiclassing that's been on since the start of 3.00... I much prefer the way it was in AD&D, or what now would be called gestalt.
I think multiclassing can be used to add flavor to a pretty vanilla build. Even a dip for a single level can add a lot of flavor to a character. For example, a street urchin rogue that gets Shanghaied into a wilderness adventure might pick up a level of ranger. The oradin is a classic for a reason.
I played a dragon-scourged dwarf barbarian 1 that became a magus so he could fight dragons with magic. In reality, I wanted to play a magus with a versatile weapon like the dwarven waraxe (one-handed for spell combat, two-handed for Power Attacking), and even more importantly, I didn't want to play a slow character (I had just finished a campaign where I played a 3.5 chaos gnome dragon shaman, and I didn't want to waste rounds closing into melee or losing all chases). I took the Berserker of the Society trait kind of as a fluke, but it let me rage 7+Con rounds per day, which was enough for 1 or 2 fights, so I could preserve spells and still be effective. The barbarian skill set also added a lot of versatility to the character: Acrobatics, Climb, Perception, and Survival; also, as a future Int-based caster, having 4+Int skills at 1st level gave the character lots of non-combat versatility (even though I rolled him up as a 4th level character).
Of course, multi-classing can also be used to set up some of the classic PrCs: Arcane Trickster, Eldritch Knight, and Mystic Theurge.
These classic PrCs are the 3.PF versions of 1st and 2nd Edition multiclasses, mostly elf fighter/magic-users and gnome thief/illusionists, etc.
