advice needed on BF4 / COD is it worth the leap to BF?

I have been playing COD since the very first one, i loved them to begin with, i have the newest one (ghosts) on xbox one, it might be me but the game has been getting worse ever since MW2, now the quick sniping in particular has got ridiculous, i still get 20+ kills per game (TDM/Groundwar) and between 5 and 15 deaths so its not the fact i die too often, what gets me is the fact someone can jump do a 180degree spin and quicksnipe with a 50 cal sniper rifle and shoot you without fully looking into the sight, this has made me lose interest in the game, they seem to have marketed for none gamers (those who wish to pick up and play instantly) why have an auto aim on an online FPS ??

i have only ever played BF once being BF2 bad company at which time i preferred COD world at war (zombies) what are the main differences between the two games Ghosts / BF4.

what are the bad points of BF4,

to anyone who says get a pc, i have one, it works perfectly etc i prefer the console version,

advice needed, as the games cost £50+ i do not fancy buying one if its going to be the same as cod.

i have checked reviews and you tube but none really give me the answers i want,

cod just seems too arcade for me now. oh why didnt they keep it like the MW 1 + 2
