FWIW the issues for at least the revision of the RME HDSPe AIO I'm
using are still not fixed. Apart from not providing all ADAT IOs and
that Ardour can't be used with plain ALSA instead of Jack, even
high frame sizes can't avoid xruns. My Scarlett 18i20 works without
xruns at lower frame sizes, while all 18 inputs and 20 outputs are
available. It was the same for my old AMD based computer with USB 2, as
it is now for my Intel based computer with USB 3.

I never checked MIDI jitter of the Focusrite, it might be that my PCI
Envy24 card and the PCIe RME card are much better in this regard. IOW I
only use PCI/PCIe MIDI, but never really tested the Focusrite.

If would buy a new audio device, I would chose an USB class compliant
RME interface.
