You would gain a lot if you were heavily loading the rack constantly or going on a tour where reliability was paramount.

Otherwise, I think a normal rack would suit a casual user just fine. I currently own a Topeak explorer aluminum rack for one of my bikes, and a Tubus Cosmo stainless steel rack. I'd put my money on the Tubus rack outlasting the Topeak rack any day of the week, but it isn't necessary for average commuting needs either.

If you do like that Vega, don't worry about the bags hitting the spokes. Ortlieb bags are very stiff on the back and use secure mechanisms, they're not going anywhere. The bag isn't going to slump between those stays and hit your wheel.
