I think you're the only who likes the user interface of LTSpice
I like it as well. It's not your conventional point and click Windows style interface, but once you get the hang of it it's actually pretty fast and easy. You just have to get used to it being keyboard driven instead of point and click driven. On the other hand, Eagle does not use a conventional point and click interface and I find it quite kludgey at times. I never feel that way with LTSpice.
Back then, when I used Eagle (switched to kicad recently), I configured the Eagle shortcuts to mimic the LTSpice ones. LTSpice and Eagle actually have conceptually very similar user interfaces. Both don't have an idea of a 'selection', they just go command, select objects, done.
