As long as don’t know that there is anything better you will love 1080p. Once you have seen 2k you don’t want to switch back. Especially on bigger screens.

On the TV I like 1080p still. I remember the old CRT TVs with just bad resolution. In comparison 1080 is a dream.

However if the video is that high in quality you will like 4k on a big TV even more. But if the movie is only 720p (like most DVDs or streaming Services) then 4k is worse than 1080p you need some upscaling in order to have a clear image now.
