Over the last years I have been using Mint Mate and was happy with it. But it turns out they don't care about security at all. They have easy screensaver bypass bugs open for years and don't do anything about it.
So I will finally switch. Probably by installing some Debian non-free image.
Any suggestions which Desktop Environment I should choose? I cannot imagine switching to something that does not have a taskbar. And most of the new desktops seem to have stopped providing one, right?
