I prefer manhwas but I like mangas too.
I started with webtoons and then manhwas and stuck to reading only manhwas for quite a while, now I've started reading mangas too and I really like them but I still prefer manhwas cause all my favs are manhwas, and they're my favs cause they are plot focused and romance is a subplot, i haven't found any such mangas so...┐( ̄ヘ ̄)┌
I'm more of a manga fan ^.^ You tend to find more diverse subgenres in manga than in manhwa. Like for manhwa, fantasy seems divided between isekai or dungeon crawlers but manga has more variety. Plus I like the layout and lack of colour manga has compared to the scrolling format of webtoons.
Also this is more of a personal problem, but I find it easier to find new unique manga as compared to manhwa.
Strictly talking about BL/shojo, I prefer manhwa, because as someone alr said they're more plot focused and not rushed unlike one-shot manga. More developed. In general, Manga seems to be reserved in expressing their love due to Japanese culture i guess. While manhwa is more expressive since korean are more open with affection.
Oh I understand! Reading manga on a phone or small device tends to be a less fun experience because of how many details manga will have. You'd probably have better luck reading slice of life or non-action manga, they tend to be less cluttered. Here's a few slice of life I like:

Between mangas and manhwas, which one do y'all prefer more and why?
