I prefer the old/pre 1.14 textures of the game, and it's NOT nostalgia talking, I do actually find them better looking

I don't know how best to explain it, but I'll give it a try

(Disclaimer: I do NOT think that the modern textures are bad, the art team did a very good job with them)

Minecraft is a blocky game, with hard edges, there's no circles or anything smooth going on, and the old textures really reflected that (at least for me)

The new textures have a lot of smoothing and gradient, and while they look great, they make the game look a bit too smooth and like a painting, it doesn't feel as much of a game anymore compared to how it used to

I like the simpleness (if that's even a word) and sharp looking textures of pre 1.14 Minecraft

If you do prefer the look of the modern textures, then more power to you
