Both definitely I started with a warlock and played months with it. I created a Titan because I wanted something new. Wasn't sure I liked it but I discovered its incredible power and usefulness. I created a hunter and felt so weak but started to have real fun once I invested time. All classes are good, really. It is such an exciting moment when in a raid or in a fireteam you have three classes playing together and you see how they add value to each other. The Hunter runs invisible and stabs adds or takes his golden gun out to save your life, the titan throws a bubble or saves the day by smashing stuff, the warlock cleans a group of enemies or simply puts the room on fire and resurrects to either save the team from a wipe or simply to avoid having to be picked up by another guardian. They all have different jumps, different perks, they move differently, they feel different. I really like them all. Try them and decide but don't give up too quickly, it takes time to get used to them and find [u]your[/u] style.
