I recently sold my Moment and was stuck for solo shelter options, and oddly all of my candidates were MLD. Solomid vs Duomid vs Trailstar. What follows is wholly my personal opinions and preferences, so take it with a pinch of salt.
Eventually I decided on the Duomid because what I was looking for was as close as I could come to an all-purpose 3-season solo shelter, and I thought the Duomid most closely fit the bill.
I chose it over the Solomid because I was willing to suck up a 3.5oz weight penalty for the extra room- I tested out both and found the difference in room to make a significant improvement in quality of life, and those paltry extra ounces were well worth it. Lots of space for contorting around to get into a bivy and bag, store shoes/pack/etc., or just get out of the rain and still have space to dress/undress (which came in very handy on my recent San Juan Wilderness hike). A solo hiker could certainly cook in it, too, though I have not yet tried this. And, of course, if you were hard-pressed it can fit two people if they are friendly.
The Trailstar, as many said, does not seem to be designs for any significant snow loading, which is potentially an issue here in the Rockies even in summer. I guess I thought that the Trailstar seems a bit more "specialized" than my "all-purpose" Duomid, if that makes any sense- it is THE tarp for wind. Even then I have a hard time believing that it is SIGNIFICANTLY more wind-worthy than a Duomid if the Duomid is fully staked-out. I do understand the appeal of it's simplicity, though. That did tempt me. But the Duomid has more headroom, too. Meh- pick your poison.
IMO the biggest advantage that the Solomid and Trailstar have over the Duomid is that the Duomid can't use a trek pole as it's center pole without a pole jack. That would be ideal- I'm into simplicity.
