OK, I'll toss in my $0.02.
The most important 950 features for me: 3, 4, 10.
One thing that really interested me was the analog bypass on any input. Very cool for stereo music listening with a CD player equipped with a very nice DAC. The various processing options also caught my eye as a lot of fun. The extra digital inputs (primarily the extra coax) will allow me to do some things I can't currently. . Other items like the extra digital inputs, the 24/128 DAC, the crossover features (until I get a sub I couldn't see full benefit of that one), and the HDTV switching are nice for me from a "future expansion" standpoint, although not necessarily immediately useful.
Items 4, 8, and 9 on the 1050 were probably the features that originally convinced me to try an Outlaw product, by the way (along with the 1050's price).
