Troll is probably the best, although all the high powered races are also great: VS, Gargoyle, minotaur. Troll/VS are best with statue form and unarmed, gargoyle or minotaur have much more flexibility and can take up weapons or unarmed, and can use blade hands or dragon form if preferred.
Ogre is also a very powerful option, which can again go either statue form or just train a weapon. Statue form with GSC is an option but I've never bothered with it. I'm generally wary of using a 7 aut weapon in statue form, as that means your final swing is 10.5 auts, which is rather slow. Adding 50% to unarmed (5 aut base) isn't nearly as bad. Of course you probably won't be at min delay as soon as you get statue form online, but you should be able to take it to at least 7 aut or lower pretty easily, by the time you have statue form going. You still get the huge hp and large rocks, but you lose the claws and regeneration, which are the two reasons troll is a stronger statue form race.
Barachians are also probably very strong, I've tested a few but haven't really played the race very much yet to confirm, but seems like a good fit. +1 unarmed is pretty nice if you're going to commit to the slow life with statue form.
If you do go naga, use blade hands. They're still very strong once you get them 'established' but they're now hell to get through the early game. Back when I highly recommended them, they had constriction from level 1 which made the early game a lot more bearable. They're still really fun once you finish lair, but that's quite a bit of floors to get through with a fragile character.
If you're really okay with the "weak early, strong later" thing, I'd recommend octopode EE, IE, or TM. If you can manage to get ice form online it's pretty decent right up until you get statue form going. Eventually you'll be strong, but there's a reason why octopode has one of the lowest win rates of all species, that 1 ac for early game is rough.
If you want to troll the forums, use a felid. Really, who needs fast movement when you have 50 ev! I'm not actually kidding about this:
