>>48492938BW2 is rushed and mediocre imo
X&Y is good (not as good as anything before FRLG but still good) but a bit short
ORAS is complete ass, don't bother
SM/USUM is also rushed, plus they tried to cram USUM content instead of giving it a separate series
SWSH is on-going but it's decent so far, however it's once again rushed because of how fast Game Freak is making new games now
if you're going to read any of them I suggest XY or SWSH, you don't really need to read the previous series to understand either of them
