What types of problems are you facing? It's one thing to say that you think developing for GB was a mistake but please give some examples. My OG hadles GB just fine. I really haven't had any issues at all besides a random reboot here and there. No big deal to me though. I am currently running PEGB but have used CM, LGB and most all the GPA's and have settled on PE for now. I didnt have really any issues with any of the ROM's just prefer PE at this time.
I work in IT and have to say that 99% of the time its END USER ERROR! Go back to stock or develop your your own ROM instead of complaining.
