Which is easier to learn? Korean or Japanese?

For you I think it might be Japanese. You don't actually even need to learn the kanji because you already know them, you just have to learn the Japanese readings (which you'll learn by just practising vocab so actually you don't have to even look at kanji learning sites, lol) but I don't know, Korean might be easier in grammar etc. but I guess they are pretty much same so it's up to you but I'd say Japanese.
