For some reason "ourselves" sounds better to me but I would appreciate your opinion.
"There is and always will be betters and worsts than ourselves (us)."
"Betters and worsts" doesn't make sense. What are you trying to say?
Please don't use non-standard abbreviations like "Thnx". It is not a word. If you must write it at all, write "Thanks".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
