I don't personally have any of the silver surfers, I have all quality cage chin spins as well as one leo braun for my prairie dogs (who don't use it, naturally, so the chins got that one as well).
Between those two, I'd say the leo braun is quieter, but then, I feel like the higher price (it ended up being $145 for me for the wheel + shipping) should denote higher quality... which it probably does.... but that said, I can't say I think it's really that much better than the chin spin. I have enough wheels for all my cages now, but if I was to buy another wheel, it would be another chin spin, as I feel like the two wheels are comparable. That said, I've only had the leo braun for less than a year, so its possible with more time I might think its better, but at the moment I'd say it's comparable to the chin spin, just a higher price.
