I have the same feelings about both.
The first "computer" my family had was a VIC-20 but I was so young I only played Congo Bongo on it. After that, my brother won a Tandy 1000HX in some sort of contest in the very early 90s (91, 92 probably), which was obviously pretty outdated by that time. At some point in the mid to late 90s it was given to me, but by then it was so old and I had no idea what it was capable of that I didn't use it for much. When I saw "256K" of RAM on startup I knew it wasn't a gaming machine of any kind... if only I'd known about the huge catalog of Tandy compatible games that were probably readily available online (we didn't even have internet at that point). I would definitely take a Tandy 1000HX if one fell in my lap, though realistically, it wouldn't be significantly different from my PC 5150 with a 5153 monitor and an EGA card. I would like to experience that Tandy 3 Voice music again though and hear it in some games, as I had never actually gotten the chance to play a game on the 1000HX, as crazy as that sounds.
I have also seen TI-99s show up for years, often times with big piles of games and software. I guess I have just read so many things about them being underwhelming that I've never thought of getting one... that and I have way too much stuff as it is. It takes a concerted effort to keep my IBM PC-compatible hardware collection in line... then someone had to give me a pile of working Apple II stuff a few years back, and then last year a friend gave me his old PS/2... arghh...
