Beastmorph - For beasticks. The only serious thing you're missing out on is persistent mutagen, but you're getting pounce at level 10, and you're only really losing poison immunity and swift poisoning.
Chirurgeon - You're not losing much, but you're not gaining much.
Clone Master - The big problem is the amount of time it takes for your archetype features to work.
Crypt Breaker - If you absolutely need a trapmonkey for your group, you might consider this (or if it's an extremely heavily undead-focused campaign).
Grenadier - This is a solid archetype for bombers. You're getting things that you almost definitely want (precise bombs), losing things you don't care about (Brew Potion), and getting some fun new features (Staggering Blast is brutal).
Internal Alchemist - Losing Int to bomb damage is bad. There's nothing to cool to live without here. Uncanny dodge is nice.
Mindchemist - Not losing much (for a bomber or support alchemist) for an incredible bonus to Knowledge checks and Cognatogen.
Visionary Researcher - Not losing much, not gaining much.
Preservationist - Summoning is a powerful ability to have in your back pocket.
Psychonaut - Wouldn't be quite so bad without all the penalties to bomb damage. Some interesting extracts, still.
Ragechemist - Possibly interesting for a boss fight (another way of disabling the BBEG), but pretty terrible for a PC. You do not want to give yourself another weakness, particularly one as simple as "Hit it and it goes comatose."
Reanimator - Whyyyy so many penalties to bomb damage. It gives you absolutely nothing for the first 6 levels, too, possibly showing some of the worst archetype writing in PF (most of which give you at least something small from the beginning so you feel different from a standard member of your class. I love undead. I love Herbert West: Reanimator, by H. P. Lovecraft. I love the
Dr. Reanimator movies (YouTube link). Despite the name, this is a terrible archetype.
Vivisectionist - Suddenly, you're a rogue with quasi-6th level spellcasting. An excellent archetype, but it needs to be optimized around.
