i have a titan level 28 but on an xbox thats not mine. Help me

so here is my problem which I will go into greater detail about in a sec, do I go gunslinger (hunter) or striker (titan)? so when I first started off I was a hunter and my brother uses a titan and I really liked hunter because the double jump throwing knife and golden gun but then my brother wanted help ranking up so in the last five or six days I have been using titan. I started to like it as the super is good as I can take out a whole team that's on a flag. the melee is not too bad and also the double jump got me higher which in situations that were a problem before is no longer a problem. now I will go more in depth about my playing style and guns I will use so primarily I like jumping around going where I like with my mida multi tool and then in bad situations switching to a fusion rifle. I like rather than hopping on flags to go somewhere where I can use the mida and get a couple of opposing players off the flag allowing my team to cap it. I also prefer a stronger melee which the titan gives. but I also like the fact that I can quickly through a knife at someone and run off get away. so now I have summed up the guns I like my play style and something I like about both classes, now its for you to try and help me, feel free to ask me added questions about this if needed. PLEASE HELP ME!!
