Alright so I'm thinking about learning Irish or Welsh. Which language is more easy to learn? There are some facts to consider:

I'm English and I can speak English, Spanish and Korean fluently. And I can read/write a little German, French, Italian and Japanese.

So what do you say? I know Welsh is a bit more widely used and probably more benefial for business but that's not what I'm asking. I just want to know which is more easy to learn.

Thanks :)
Oh and if you recommend Welsh then tell me if I should learn South Welsh or North Welsh.
Both are hard to learn, yeah I know, that's why I want to try.
