I guess thats a bit subjective. It will have a different look and feel because the sensors are different, but I really like the 100s. I find it is able to resolve fine detail better and high iso images are much cleaner, but noise ( or lack of it) and sharpness isn't everything. I still prefer the images I got from my Leica X1 even though many people will knock it, the images had something that you couldnt put your finger on. The x100, had a similar feel.
I havent really used the camera enough to form a proper opinion, but so far, things are looking good and I dont feel I am missing the quality of images I used to get with my x100.
Ask me again in a few weeks, I may have an answer then.
