Been reading through the new Technomancer stuff and the Cache Hacks look interesting. Is it worth taking over the normal Cache Capacitor? If so which one looks the best bang for its buck.
It's super better than the normal cache capacitor, which is very bad. All of the COM options are superior to that.
Which one depends on what you want to do.
I think Devastator is a trap for people who think infinite low level offensive spells are more useful than they really are, but if you want the playstyle of casting instead of shooting, it's fine. Take Harmful Spells and the other offensive metamagics and go to town.
Genhacker's Cache is an upgrade on the standard cache, still focusing on buffs but dropping most of the terrible ones and adding permanent polymorph buff as an option plus infinite baleful polymorph debuffs.
Holographic Artist's is my favorite, great defense and utility. If you're looking for power and flexibility rather than to match a preexsting theme idea, I think this is the one.
Junker's Cache is fine to support a theme, but suffers from the fact that Junk Armor 2 and 3 aren't actually real spells and from Junksword doing subpar damage even at your top spell level, let alone underleveled. But Detect Tech, Supercharge Weapon, Microbot Assault, and the 3rd level junkbot spells are a mix of useful and fun to support a certain concept.

I'm liking the look of this one too. But how does it work with "Summon Creature"? Does the creature stay out or is it just cast it as much as you want?
It doesn't have an asterisk, so it stays out. You can resummon the same creature with 5 minutes work if (when...) it's killed, just like a normal permanent cache spell.
I wouldn't say that the standard Cache Capacitor is useless. . . its just mostly useless for adventurers. It makes sense as a thing people would have and use in the setting, just not heroes out doing heroic heroism.
Level 6
Detect radiation - pretty useless, there are tech items to do this and even the real world has geiger counters and radiosensitive film
Disguise self - increasingly useless as you level and the DC doesn't increase, plus you could just use a holoskin and avoid the will save issue
Keen senses - this is good
Unseen servant - c'mon, it's a 1st level spell and already has hours/level duration, and permanency is not worth much on something that has a 15' speed unless you're incredibly sedentary and lazy about trivial tasks
Level 12
Darkvision - Almost entirely useless as an option, your natural duration is already 12 hours. Are you really worried about running out, having to burn a second spell, or having this dispelled just to save money or slots on an augmentation or armor upgrade that would have saved you a spell known and a spell slot?
Lesser resistant armor - Not useless, but there are better nonspell options to cover this. You're either saving money, armor slots, or feats, and only the latter (which isn't a great feat on a 3/4 BAB class) is worth more than spell known and a spell slot every day.
Life bubble - SO,SO USELESS. This has days/level duration! Are you worried about having this dispelled in a situation where you can hold your breath for 5 minutes to bring it back up? It's a 1st level spell effecting numerous creatures, recast it!
Spider climb - You're level 12. C'mon, you don't have Force Soles Mk2 or any of several better options yet? And it's a situational 2nd level spell, just cast it when you need it, very rarely will that be on yourself twice in one day.
Level 18
These are all quite useful. They are also all not available before level 18.
