[Need advice] is Xperia T a good buy? topic

well i lost my xperia zl and need a new primary phone quite urgently...cant decide between xperia t and sp (yes in a bit of tight budget)

what am basically after right now is the display and battery life...also how does the xperia t perform as compared to sp ..is it very noticable? (tbh i would prefer a little low graphic detail than overheating and throttling)

my pros for t :

Roms i like are available :P
way better deign
cheaper

worries about t:

performance
battery

any suggestion is appreciated :)
