I am currently developing a 2D side scroller for Android using OpenGL ES. The UI drawing routines are very slow and resource consuming, which creates a lot of memory to be dumped regularly by the GC, which causes hickups every 2 seconds for up to 1 second (!). OpenGL ES allows me to render at a consistent 60 FPS (on G1) with no new allocations per frame.
Actually, I use a combination. Bitmap is used for caching blocks of the tiled map and converting it into a texture that I can quickly draw with OpenGL ES. The GLSurfaceView, I believe, always renders as fast as possible, which is not suitable for applications that are not constantly updating the entire screen every frame. The UI (or a manual implementation of OpenGL ES) should be used for infrequent updates or small area animations. You shouldn't use the power hungry GPU unless you need to.
