A theme may help the look. Hit the GALAXY APPS app on your device. Many of the themes are free.
Another option is to try a custom launcher. You can customize icons, backgrounds, menus, homescreen folders, gestures, etc. With just a few exceptions, you can customize almost everything and make your device look and feel exactly how you want. I switch between Action Launcher 3 and Nova Launcher, and using that along with a theme, the only thing that I can't touch is the white background of the notifications shade.
If you can make the phone that you say "finally works as it should" look like you want, you could save a ton of cash next month.
