I've had iOS7 on an iPad 4 for over 4 months with very little issues. The very first beta release was a bit laggy, but has significantly improved with the last two releases.
I've tested and still using iOS7 on an iPad2 and iPad3 as well with no issues whatsoever.
I recommend hard reseting your device.
I have not tested the latest GM release. It is my understanding that the GM is the same as the last beta release.
