TL:DR ubuntu is best choice for beginners,i tried the most 4 recommended, and decided ubuntu. You shouldnt really care about interface, but more about your stuff working (packages i dont know about working and those repositories/dependencies not missing) i think i have a grasp of those, they exist for the purpose of software reusability. I literally installed ubuntu, didnt really like the looks. Tested kubuntu, looks nice but a lot of packages are missing and felt like windows after while. Tested elementary OS, its fancy AF but has issues with gnome(thats what the internet said) Tried linux mint cinnamon, feels like when i almost killed my old windows xp computer with themes. Bad memories, avoided it since it kubuntu also looks like windows and liked that tomorrow. Tomorroe i reinstall ubuntu (had to reinstall so i can get my mbr back for the sakes of windows updates, and will use easyBCD to chainboot grub (legacy) which in turn will start ubuntu. Here is a tip, wanna have something that works? Ubuntu. After a while you could change, just dont do my mistake.
