Is it worth getting a Korean lever?

I recently bought a new arcade stick, and I'm looking to upgrade the parts. I've decided on some buttons and art but I'm still undecided on what lever to buy. I quite like the lever that came with this stick (a Sanwa clone with a square gate). I've always played on square gates before, because I liked the firm diagonals, so I was going to get a Sanwa JLF and be done with it but wherever you go people tell you that Korean levers are the best for Tekken by far.

Price difference is negligible and both would be just as easy to install, so I guess in short my question is, is it worth spending the time adjusting to a Korean lever when I'm so used to square gates, even if I don't play Mishimas?
