Running it on my laptop and my desktop, it's fine.
If you really miss the start menu grab
Classic Shell.
I don't really mind what the screen looks like for the 3 seconds I'm typing in the name of the application I'm starting, so whatever.
Winkey+X is great. Much quicker access to anything you need than going through the start menu. New task manager is great, no need to download a third party one anymore.
Built in hypervisor is nice for running a virtual machine or two, but I'm just so used to virtualbox I haven't messed with it yet.
Don't really get the hate for it, it's like 7 but better.
