Here's my take on it FWIW. I've had standard double, a triple (30/27 low gear) and now a compact double (both 34/28 and 34/32). What I've been able to learn is, for me, the triple with its wider stance (q factor) is a problem for both my knee and hip on the right. I find a narrower q factor works better for me. The gear range I am able to use with a compact is better for climbing. It shifts marginally better and the steps between the gears are really not much different than the triple. I have the option to use the bike with the 11/32 cassette (requires a mtb rear der.) for the really steep stuff. That gear is lower than the 30/27 I used to have. I can in the future add an 11/34 or 36 cassette for even lower gears. 34/36 would actually be too low I think. It would be better to lose weight IMO. lol

What I give up with wide range cassette is a 16 gear. I do miss it at times on the flats. But, I could just replace the cassette (11/21) and chain for a flat ride if I wanted, though I almost never ride the flats. A 50/11 gear is taller than a 53/12. So, to summarize , I think the compact geared bike can be setup however you wanted it to be. Having a few spare parts would allow it to be tailored to just about any ride.

Since you are looking at DA 7950 I guess money isn't as much an issue. My wife's bike has SRAM Red with a compact and XX rear der. and an 11/32 cassette. She loves it. My Di2 bike has the compact crank and an 11/28 cassette. Works great!
