XU4 or Rock64?

I am locking for a faster replacement for my pi3. I am using it to run multiple docker container (Home Assistant, Resilio, InfluxDB). So I am especially interested in fast CPU and more RAM. Looking through the various pi alternatives, I am struggling to choose between an Odroid XU4 and a Rock64 with 4GB of RAM.

Any suggestion on which one would fit better for my use case? I am not that interested to run it as a NAS, so SATA is not important. I also considered the ASUS Thinkerboard, but the software support seems to be lacking behind the other two.
