qflash vs einstein picture request

I am looking to purchase either an Einstein 640 or AB800 for us at home in the living room bouncing off the ceiling. Currently I have the qflash T5D-R, which works well, but is a little under powered. When I use it at full power, the flash duration is too slow and I see motion blur of kids. My concern is the size of the Einstein or AB800. Does anyone have pictures of the qflash T5D-R and the Einstein 640 next to each other?

Thanks,
Charley
