Mint is based on Ubuntu, so you could try Ubuntu itself without the Mint stuff bolted on.
Ubuntu asks you what you want pre-installed when you’re setting it up.
And since Ubuntu has all the same flavours that mint does (and more), it’ll look like what you expect it to. Modern Mint uses Cinnamon whereas old Mint uses Mate, so just choose the one you’re already familiar with.
Ubuntu is great.
The company that supports it (Canonical) usually makes an annoying decision that goes against the community’s preferences every 3 years or so, but they always eventually rescind it.
The last decade of annoying decisions is changing which desktop environment is considered “default”, and a bunch of developers time wasted on an ubuntu for phones which never released.
Their current “annoying decision” is pushing Snaps which are just a way to package apps. They’re okayish, but they run apps slower than the other standards (Flatpak, Appimage, or just installing through a package manager) and Canonical is in charge of the place where Snaps are downloaded.
Most people just download Ubuntu, uninstall Snaps then install what they want.
So yeah, ubuntu is great, the company that supports them usually puts one annoying thing in at a time every few years that the community turns off and ignores.
