With WinApps you do the bulk of the setup manually, and there’s no cohesive interface to bring it all together. There’s a basic TUI, a taskbar widget, and some CLI commands for you to play with.
WinBoat does all the setup once you have the pre-requisites installed, displays everything worth seeing in a neat interface for you, and acts like a complete experience. No need to mess with configuration files, no need to memorize a dozen CLI commands, it just works.
