I've been a few times in different locations around the world. They were blander than WeWork and had about the same level of community. It was just an office. WeWork branded itself as something special... it isn't. It's a slightly nicer looking office (with beer* maybe). Regus is profitable and has a valuation in line with what they do. WeWork... doesn't.
Yeah. Regus offices are dreadfully bland. Also, they nickel and dime you for every little thing (you want an hour of wifi for that meeting room you booked? it's going to cost you...). Regus is also very expensive, as office space goes.
