After meet MeeGo i can say, i won't comeback to Android anymore.
I think i'll only change it by Tizen or maybe maybe some Lumia.
Android is good but it's emulated Linux, thats the reason because it will never be fast.
You have to decide what you want., if you want to develop try MeeGo you have a lot to develop. In Android there's a lo of development of course, only if you have a great idea you can excel.
But it's your choice after all.
Anyway, your choice will be good. There's no wrong answer
