620 or Rose Bowl Board?

I tried posting this yesterday but I don't think I did it right . . . I'll try again. I have Miggle's Original Electric board and a 620. It seems like players move a bit more smoothly on the Original board than the 620. It looks like their newer Rose Bowl board is made the same way as their original board, only bigger.

So, here's my question: Of those of you who have played on both the 620 and the Rose Bowl Board, which do you like better? Do players move better on the Rose Bowl board? Thanks, Brian
