gettin a new cellphone..any suggestions.?

okay so my last phone got old and boring so now i'm getting a new one. but i dont know what kind to get. first i saw the samsung comeback and it looks pretty nice but i really wanted a slider phone so i looked at the rant and it seems pretty cool. but i'm kinda stuck between the two. if you have any better suggestions u should probly let me know. if you know what the rant and the comeback are like, tell me. i just need a new phone and really fast because i CANNOT live without a phone, it just doesn't work with me. so if you have any suggestions, comment.
