Except here’s the thing about that; Ubuntu MATE is pandering to old Ubuntu users by providing something similar to Canonical’s OOTB experience, pre-Unity.
I will say, however you had tried a Ubuntu system at a fortunate time; MATE Menu is based entirely from Linux Mint’s mintMenu, so much the original author of mintMenu is in the software’s configuration files. For some time, mintMenu had been more difficult to install because of odd package requirements which hadn’t been easily satisfied by the common user, and because of the whirlwind of UI changes lately it’s been pretty hard to install anything like it elsewhere.
Nonetheless that is why MATE Menu was compiled; to strip the Linux Mint identity from it and make it a universal, generic Windows-like menu for all systems using MATE. Had you been a user five years ago you’d probably be on Linux Mint just to have the mintMenu, since it would be the easiest route to a Windows-like user experience outside of Windows. (complete with security issues and senseless software decisions, depending on who you ask about Mint.)
Though if you were around when Ubuntu still used GNOME 2, you’d probably be whinging about how you need to install mintMenu to make Ubuntu feel like Windows. Which, dare I say would make you the laughing stock of any Ubuntu (or Debian) community.
