Lightbulb [Q] Should I use Flash / Adobe AIR development of Games?

Hey Guys, good afternoon. I need to know if it really worth developing mobile phone games using Adobe AIR. Did some testing with various animations and realized that there is a delay, but not both. What I'm afraid is to invest time and money, and be shattered at Play Store by putting a slow game. Wanted your opinions on the subject. Thank iOS and Android platform.
