What Linux distros offer more attractive designs?

Your choice of distro doesn't limit the desktop environment or themes you can use. If you're looking for something with a more skeuomorphic design, I recommend trying elementaryOS; it has a unique interface that's quite appealing. For other desktop environments, KDE is super customizable and you can find many themes to bring some life into it. XFCE and LXQt also have decent options but might require a bit of work to make them visually engaging.

When you're exploring visual options, remember that it's often more about the desktop environment than the distro itself. If you're using Mint with Cinnamon, that's a good start, but if you want to really tweak things, KDE Plasma is known for its extensive customization. Some people also have great experiences with Gnome if you're willing to install a few extra extensions.

If you're after something really eye-catching from the get-go, check out Garuda's Dragonized edition! It's definitely not to everyone's taste, but they've cranked the visuals way up, so it might be right up your alley.

You can actually install multiple desktop environments and switch between them at login! Aside from Cinnamon, KDE might be your best bet for a Windows-like experience. I used Mint with KDE for a bit and liked it a lot.
