Double the ram, twice as fast, gigabit ethernet. 4k. Still usb 2.0 though. Much riskier on OS and software support/community though. If starting out I would go Rpi. But this is defo a very well specced little board.
The specs might be great, but without proper (DKMS) drivers and/or source code you can't make the chips do anything. Especially when the vendor decides to drop software support a year from now...
it is still pretty hard to find ARM with USB3 these days for DIY
I had the same issue (no ARM+USB3+gigabit boards) so I had to build a board that had all of that plus mSata and minipcie.
I just use celeron boards (mini-itx) that has everything I need and is still low-power

I just posted an Ask HN about it. I'm going to produce the boards as part of the Make/100 kickstarter project
