Question

I have a few questions on gamertags and want opinions on mine. First why do people put to i's in there name like this x FiireMan x. dont know if thats a real person just an example. and also why do people put i's before certian letters like this IE P ii IC. that one has both. And now for my gamertag my current gamertag is x V iSi O n zZ add me if you want. My new ideas are I pRiM3xTiM3 I, N 3 W x 3 R A, and H a R iVi o N y. Please tell me which is best. Thanks :)
