If camera is a factor for you, then you should go to V8. It is superior than T11's.
Other differences are, V8 has NFC, also has a rear touch panel (useless for me, but others may like it) and T11 has bigger battery and the 900mhz band at 3g (depending on your country it may be useful).
Also both are big phones (v8 is bigger) and if your hands are "shaking" then you will need a case. If a free fall without case occurs, then the law of nature says that the smaller could get less damage, but this doesn't mean that if your T11 fell down it will survived!
PS iNew V8 is running an almost Vanilla Android KitKat v4.4.2
