I had a Henry AR7 for a while. I always wanted one but after I got it the novelty wore off rather quickly. It functioned great, never jammed and shot where I pointed it. The trigger was terrible though. I don't have a 10/22 TD but I have a regular carbine that I added a Volquartzen Custom hammer to to reduce the trigger weight dramatically and then installed tech-sights. It was a great shooter before and now I am in love. I'd like to get a TD and do the same work to it.
Also if this craziness ever dies down you can get good 25 round mags for the 10/22 where the aftermarket larger capacity mags for the AR7 aren't very good.
I don't collect guns, I accumulate them.
