There are experimental roms and there a stable roms. You use experimental roms, test it for a day or two report bugs and go back to stable roms. This rom is super stable, minimal bugs and excellent for daily use. Never played games on my android phone while travelling but with this rom installed I am doing everything. Battery life is good.
If you are waiting for 2.8 well I'd say you are already missing out on a super stable rom. Morever the dev is busy with his exams. Go ahead and try this rom you won't feel like switching over to any other rom.
Just take a backup of the messaging app on your current rom using titatnium or whtever. Many didn't like the new messaging app.
