Different strokes man. I like the Dj layout, the v10s have a ton of routing capability, and it’s nice to mix and match my gear. Sometimes I want 12 channels of DAW, other times I just need one mixer to do the job… there’s a ton of ways to configure but I dig this one. Everything costs money, so I decided to just build “exactly what I want” and accept the cost. It’s all relative 
Besides, no offense to B… but their products don’t get me there. The v10s came about Bc I wanted the Model1, but refused to drop 3k on a mixer PLUS 3k on a large interface. Instead I sold a UA IO and turned that cash into the first v10. Now it’s an aggregate usb IO for ableton sometimes and a Dj mixer other times.
Some other guy would totally justify the Model1 and Apollo 8Pre… and he’s right in doing so, if that’s his jam. Different strokes.
