Most LTO stuff is very reliable. It has error correction and etc. We use LTO6 half height and a HBA adapter and it was ok so far using LTFS on Windows. However support has been recently dropped and its MAC or Linux only going forward.
Most if not all tape drives are made by IBM so it doesn't really matter where you get it from.
Now, is it worth it or not? Depends. I think there are posts on the internet on the cutoff number of TB where its worth it. Not sure on 80-100TB though. LTO8 drives are pretty expensive. Media is cheap though, compared to HDD and much much much more durable. As long as you store it in a proper environment. Dust free, moisture free. Etc.
