hahaha , whatever makes you happy man !!
yeah obviously stock moto e is so much better thats why i rated it comparable to moto E and not better despite x2 having autofocus + flash because no google services and skinned theme takes the pure android factor away..
for techies who can install a custom rom x2 is the best smartphone under 10k till now ...
the difference between the 2 soc is too much
the old cortex A5 was on 45nm .. this is on 28nm .. plus the performance difference, these newer cortex A7 are faster than cortex A9 ( s duos 2 )
especially the GPU .. the gpu is actually 200% faster than the predecessor
so your example is actually wrong ... it's like getting A star to replace 800 where the engine is so much powerful especially when it comes to playing high end games... check moto E gaming performance .. modern combat 4, Asphalt 8 no lags...!! get what i am saying ?
Regarding build quality , Moto E itself has poor build Quality

absolutely not mandatory !! if you are on stock rom rooted and unroot it you don't need to flash anything
depends on different phone models as well
