I just sampled both, and I have to say I really like Ultimate! It's sweeter, and much more pleasant than the regular Code. Ultimate isn't quite as musky in my opinion, and I feel like I would be more likely to use it on a daily basis compared to the regular Code. I think this is one of the few times I've seen a company make another type of cologne from the same line that is actually better than the original. Honestly, Ultimate will probably be my next buy.
