While the trailstar has some really neat attributes, I think the vast majority of hikers are better off with a mid. Sure the trailstar is the ultimate high wind shelter, but the other mids are great as well, and they are much quicker to pitch, ofter full 360 protection, they're lighter and nicer to get in/out of (no kneeling). So unless you regularly camp in really harsh conditions or want a huge shelter, I think a mid is likely the way to go.
I personally own a DuoMid (cuben prototype, 11.4oz). I haven't used a solo mid, but I suspect the Duo is well worth the extra few ounces. You can sleep in the back half of the pyramid away from the door, so your stuff doesn't get wet if you open the door in the rain. You also have a nicely sized vestibule for your shoes, pack etc. It's a very well appointed solo shelter. With the solomid you give up headroom (which also translates into less useable length, due to the slope of the walls), you lose vestibule space, you have to worry about opening the door in the rain, and the only upsides are slightly smaller campsite selection requirements and a couple ounces (and dollars) saved.
I haven't used (or seen) a solomid (or trailstar) but I've done a lot of research on the topic and think for 80% of people the DuoMid is probably the right call. Some gram counters (or people who spend very little time in their shelters) will prefer the solomid, and a few storm camping fanatics (or acrobatic sleepers) will love the trailstar. The trailstar is a really cool shelter. I love the idea, but for me simplicity is huge and a mid epitomizes that.
