Here is my experience with my two (a 5yr old Ringo and a 1 yr old Ella)
Smelly: not necessarily smelly but they have a distinct odor to them, Ringo more than Ella, you get use to it and it isn't very bad IMO
Drooling: Ringo yes but not that bad, mainly just after he drinks or around food and Ella doesn't drool at all really
Snoring: neither of mine snore, breathe heavy sometimes but that's it
Disobedient: I wouldn't use that word, I would use the word stubborn more. Mine are both very food driven so if I have treats I have their full attention unless there is a rabbit near by which always trumps over food here

We got Ella as a puppy and were able to teach her all the basic commands and she does pick up on things rather quick. Ringo we just got in March and he doesn't know as many things and is definitely slower to pick up on things but he's never a trouble maker so I don't have any problem with him.
Walking: both mine are big on smelling so walks can be frustrating, mainly if I am trying to walk both at the same time though. But if you go for hikes in woodsy areas they are fine cept they are always smelling which I don't mind. With mine if I'm wanting to just go for a quick walk around the neighborhood I walk them in the street because other wise they are pulling and smelling the whole time. I use the Gentle Leader with Ella which helps her walking a lot too, I have much more enjoyable loose leash walks when she is wearing that
Both of mine are very friendly and very cuddly, they LOVE to snuggle and be close to me and are always excited to meet new people and dogs.
Of course dogs vary no matter the breed. Ella and Ringo are complete opposites pretty much Ringo is low energy and kind of lazy and easy going and Ella is hyper and curious and has ADD

They are both wonderful dogs though and everyone that has met them loves them as well
