Different trend in S3 aosp custom rom

choosing which custom rom to flash used to be a VERY VERY difficult process back in the days during ics and jellybean era
all aosp custom roms offer similarly great features and it's very hard to choose between them.
i remember the internal conflict i have to decide between cm,aokp,slimbean,paranoid android, rootbox, etc.
because they are all so great. and the deciding factor is whether they have custom features that i actually use
i hop between roms and loved all of them. the last dilemma i had was between aokp and slimbean, and i ended up with slimbean in the end

but now, for kitkat roms, there doesnt seem to be any struggle in choosing rom.
temasek rom seems to rule while others are lagging behind sooo much in terms of features.
I'm talking about usual custom features that exist all the way back from cm9.
but other than temasek rom, seems every other rom cant even properly implement their usual features from their own previous android version.
example,slimkat and aokp kitkat barely have half of their previous jellybean features

everytime i try a new kitkat rom, it doesnt last more than 1 hour before i restore back to temasek.

do you feel the same? is it because s3 is old therefore rom development is not as competitive as before?
