If you seriously want to be stuck with the single most popular solution, you're welcome to use Windows. Anyone using Linux on their desktop or laptop is already part of a tiny minority. IMHO, it's a bit hypocritical for a Linux user to argue against the possibility of multiple, competing alternatives.
Anyway, there is no such thing as a single "good enough" window manager, or any other program for that matter. Different people have different requirements, which in turn demand different solutions.
