I have a 2004 Multistrada with a dry clutch and have also extensively ridden also a wet clutch 2012 Multistrada 1200S.
If I had to compare the feel I'd say the newer multi with the wet clutch is a lot more forgiving and reminds me more of driving a VW Jetta. Newer generation VW manuals drive so effortlessly and without much feedback in my opinion. My current multi with a dry clutch feels more sporty in response, more like shifting a sports car with a tight response.
That's how I personally feel about the difference - maintenance and other aspects aside. No doubt everyone is going to argue about what's better and it's probably a matter of preference. Sometimes I wish I had a wet clutch and other times I really enjoy the dry clutch feel.
Dry clutch sound is badass IMO.
