a2jmidi + alsarawmidi for jack2 are a nice combination to get rid of hw
MIDI jitter.

Are there any technical reasons why whatever method a2jmidi

I don't know if there's such a tool. But AFAIK jack would only block
the raw MIDI device when you use "-X raw" to use the raw MIDI driver in
jack. Do you need that driver? If you don't, you can use the "seq"
to reiterate: if timing matters to you, do NOT use -X raw or -X seq.
use a2jmidid -e instead.
