I can tell you I said "man react is great!" quite a few times 10 years ago when I tried it for the first time, after years of jQuery, backbone.js and Angular 1. Nowadays I still think it's great, but there is obviously no surprise and novelty about it being great since I use it every day. Like I'm sure you think toilets are a great thing but when was the last time you said "man toilets are great!"?
