doesn't look fun:
13-15 opposite 4-6, 5M332
1000 hands processed of 57490 attempted:
NT scores better on 168 deals
NT scores equal or better on 378 deals
NT one trick less on 280 deals
1NT goes down on 801 deals
2M goes down on 627 deals
8-card M fit on 722 deals
frequencies of HCP totals: [(17, 103), (18, 206), (19, 348), (20, 248), (21, 95)]
Arguments about validity of DD sim and likely competition even more so. I didn't check against par, of course.

I wonder if these results can be used to suggest that when 5332 with a five card Major, one is always better off opening up 1M vs 1NT (given the 13-15 HCP) range/

There are statistics for this online. When the major is hearts, opening 1M is not a big winner (and will be a loser on all other 1♥ openings). When the major is spades, opening 1♠ is a significant advantage on the 5♠332 hands within NT range. There are also good system design reasons for not doing it that way but most are beyond the simple comparison of a single hand type and are therefore more difficult to quantify.
