Anyone that has built their own computer (such as the OP) has enough skill to configure Win 8.1 such that 1) you never have to see Metro, 2) you never need to logon with an MS account and 3) for $3 you can have an exact replica of the Win 7 start button (StartIsBack+) ... and you end up with a better OS than Win 7. Win 8.1 is the same as Win 7 with speed advantages and an improved Windows Explorer.
I used to think the same way as you, but after messing around with Win 8/8.1 for a few months I'd now only recommend Win 7 to someone that is technically challenged or to someone that really needs XP Virtual Machine.
BINGO.
