Yes, I really think LSP has been a game changer. I started using emacs in undergrad and later gradschool mostly for the Latex support. Combined with helm-bibtex it's a killer feature set. I worked mostly with matlab in gradschool and mostly used the matlab editor. But when I needed python or c I used emacs, though it was always a slog to get to get IDE-like features working. LSP was really a game changer that let me get rid of CDET and ctags and elpy, and has let me continue using emacs now at work. If not for LSP, I almost certainly would be using clion or VScode. I will say though, the one place emacs doesn't cut it is for jupyter notebooks. VScode really is pretty killer there.
