Definitely the Mayans; if you wage war early this is THE best Civilization in C3C!
The Javelin Throwers enslavement capability will get you tons of free workers (free to aquire, and they require no unit support!), which will save you loads of cash! Also, the many early workers will improve your infrastructure drastically in the early game, resulting in an awesome early boost! Excellent for early Settler and Unit Factory cities
The early GA is a major downside, but the enslavement UU makes it worth it.
There's only 1 scenario I can think of (luckily, I haven't experienced it yet) where the Mayans would be a 'bad' choice, and that is if you start alone on a small, secluded island, not connected to any other landmass by Coast tiles.
Also, on Deity and above, waging early wars is VERY difficult, and will probably get you raped before you manage to enslave a single worker
