Re: RF 400, or EF 400 with adapter?

Optically the same.

EF works on more systems: DSLR and other systems with adapters.

EF allows use of control ring adapter (I don't think I'd use this honestly - too far back.)

EF allows use of variable ND drop-in EF-RF adapter. Helpful for landscapes.

RF has more pins and the possibility of taking full advantage of R1 and R3 speed. It might focus a fraction faster with those systems. But Canon is not saying and no one outside of Canon knows for sure.

RF has one less mechanical coupling. It should be slightly stiffer.

It's a close call. I'd pick the EF version today. For the flexibility. But tomorrow?
