John,
I would regard vDosPlus XyWrite as a mature solution, and DOSBox-X as a
work in progress. I am quite happy with the speed of vDosPlus XyWrite
and I have been rather busy doing other things, so I have not felt an
urgent need to test DOSBox-X. Given time and effort, it may become a
serious contender.
Best regards,

But I'll leave this for others; vdosplus looks to be much the better
choice, for my purposes.
