Exynos or Snapdragon, what do I gain

Hey,

I read thread Exynos or Snapdragon but it was closed without answering precisely few aspects.
I do not care about benchmarks but mostly daily usage, so is it true that moving to:

Exynos:

• more smooth system


• no other roms but based on Samsung, no AOSP

Snapdragon

• more micro lags


• access to AOSP

And here is the thing - AOSP.

As far I know none of AOSP rom is so rich in terms of useful things like Samsung based rom - I mean S-pen, camera, overall productivity which Samsung made for Note 4 exclusively as it is business serie.
So having Snapdragon we install AOSP rom and lose great camera (as AOSP rom has always crap camera software), S-Pen and other smaller things. Then we get not the Note but Nexus or One Plus One.
Is there a point in moving to AOSP rom in Note 4 and losing all these things? IMHO no if we lose them, and I guess we do.


So if we want to save all productivity, camera ect. we have to stay on Samsung based rom, where then it does not matter it is Snap or Exynos, except better performance of Exynos.


So judging is it better to take Exynos or my points are flawed?
