Mained a Titan since Day 1 vanilla. Love the versatility of the class. Defender plays a critical support role in endgame PvE (Weapon/Defense buffs, Orb Generation), Striker is an excellent PvP class for aggressive play styles, and Sunbreaker offers a nice class for both PvP (ranged offense for multiple kills) and PvE (add control). Although I feel this class is the weakest of the three. Plus Titan exotic armor choices are great. Saint-14, Armamentarium, Twilight Garrison are all top tier. And the fact that this class runs high Armor and Recovery fits my style.
