You just described me about a year ago....tweaking my S3 and trying EVERY rom available..recovering from soft bricks and so on and so on......
But then I got tired of it and stopped. I have my S4 and will not root it or flash a rom unless it provides something truly mind-blowing......
flashing roms is a sickness!
Did the same with my S3. I especially liked playing around with the hybrid roms and putting the UI on tablet mode. I haven't even rooted my S4 yet. I guess I'm in one of those "I've seen it all" moments.
The only thing I miss is Google Wallet, but I can live without it as I only used it at gas stations and occasional trips to Rite Aid.
