Gojo is one of the better Karate styles in my opinion. I've seen some bad a$$ men come from there. But I know nothing of Shorin, so I couldn't reccomend it.
Of course it all goes down to, do you like the school, which sensei knows how to teach, blah,blah,blah you all know the rest. Only reason one should choose a style between two, is if both schools are equally (or close to it) good.
