So you haven't used it, are going by what others say without your own opinion, yet you don't recommend it. At least if you used it, you could have a point to stand on, but not liking it because some website or youtube told you not to, you can't really say much.
8 is the future, it's going to get more support, it's fast, stable, fast, I haven't blue screened once or rebooted even in weeks, it's fast, and all the nice little features like the new task manager, explorer, copy graph, etc are nice little addon's.
Buy start8 for like $4 to get a good start menu and have it boot to the desktop and you never have to see the tile interface nor use it if you don't want to.
I'd go with 8, I've been using it since the public beta's started coming out and with start 8, it looks just like 7.
