The human bonus feat and skill is too good to pass up. The halfling subrace that gets a bonus feat, ghostwise I think, they are broke. Low damage and grappling is their only weakness. Elves I would put next in versitility, once you include their bazillion subraces. Half-orcs could have been cool, but I don't know if I would ever play one cause their stats suck too much, only the half-orc druid substitution levels makes them tempting at all.
I found half-giants to be pretty good, but I think powerful build got a bit downplayed, and the 2 bonus PP and stomp 1/day just doesn't compare to the goliath. They would need a higher caster level for stomp and at least 1 PP per CL to compete with Goliath.
I hate that undead are automatically immune to mind affects and critical hits. They should only get a bonus to avoid them, not complete immunity. First I think only mindless creatures should get the immunity to mind affects. Most undead have crit zones too IMO, zombies always go down with a shot to the head. Same usually for vampires and stuff. They should just get DR and 50% resistance or something. I also hate their ways to get bonus HP. Lets say an undead created in desecrate gets bonus HP, or with Corpsecrafter gets bonus HP, etc... those abilities should just grant Unholy Toughness or something like that. A bit more powerful than just one of those on their own, but a lot more balanced once you start stacking them, and that prevents stacking because you couldn't get the ability twice.
I like a lot of the template races and monster races, I think its a pretty cool option. Raptorians seem pretty cool too, but I haven't really used them yet. Shifters seem too feat-intestive, but some of their racial substitution levels are kind of powerful... maybe too good. Warforged are kind of cool but seem too world-restrictive... they have a certain flavor that wouldn't really work in some campaigns.
