I play all 3 about the same amount. Maxed them all, and have almost the same PvP K/D on all of them. The hunter is definitely my favorite and the titan my least favorite. The 3 classes feel the same to me except for some specific niches that the hunter and warlock can fill. Although I would much rather have golden gun over arc blade, I usually use my bladedancer for the invisibility. Flanking in PvP and reviving/objective stuff in PvE. I usually use my warlock's radiance for "mass orb producing" and an extra life is always nice, especially for Trials. The titan always reminded me of that one standard, well rounded assault rifle in every shooter. Kinda good for most things, better and worse in certain areas, but not many specialty roles to fill. Plus, I was always a huge fan of "spawn with a grenade" armor pieces, but the titan doesn't have that or a bolt grenade for me to use it with. :(
