I've used both - the Revs are lighter and feel "springy" on jump landings. It's a very slight difference, but it noticeable to me because I'm a little weak these days. Frankly, a little off-ice training would make the weight difference negligible. (Think about it: if
Downside of the Revs is the material used for the sole plates/blade chassis. It gets scratched, dinged, chipped pretty easily - I do very few jumps and yet, my blades look like crap. The silver-grey toned color is just the outer color - the interior color is black and it shows when the outside gets damaged. A paint marker makes it less noticeable.
You also have to dry the Revs obsessively well. The areas where the blade is secured to the chassis is difficult to dry thoroughly, so slight rust spots develop at the top. It's cosmetic, as far as I can tell, but I use my skates to skate 10 blocks of time each week. The only way I know of to really dry that area is use compressed air to "blow out" all the moisture. I settle for drying them, leaving them to warm up, drying them again and then putting the soakers on. I never "air out" my skates - just leave the skate bag open to let air circulate. YMMV
