Only one thing is for sure: Whichever one you own, everyone else is going to look like either a dinosaur or a risk-taking fool.
Tarptents are pretty affordable and have pretty decent resale value, so you're not out too much money if you try one and just can't make it work. If you can make it work, the Tarptent is a good choice for a lighter load on a thru hike. My Contrail performed perfectly on my AT thru and other hikes before and since.
