It really comes down to personal choice, as they're both different Jokers. The Sideshow Joker, imo def goes better with the Quinn that will be coming out, as the Nicholson one is so uniquely him, that the pairing would seem odd. I am assuming you are looking more for the original Nicholson Joker and not the Mime version. If correct, then I would base my decision on availability. You can get the sideshow joker now on the website, but the Nicholson Joker is long sold out, and sells for more than $200 in the after market.
