I have a lg Spicewine and am much more pleased with it now then I was at first. There is a big learning curve, after cooking on junk, which I have just about got nailed down. I think that is going to be true for any smoker you buy that is well built. If I had it to do all over again I may have gone with the smaller Sw for competition, which you haven't said if thats what you intend to do with it.
All the smokers mentioned are good but for my money the Sw is a good buy. the wsm is just small for me and I don't want to have to tend to 3 or 4 cookers at a comp. The stump is most likely a good smoker but I don't see the need in having a hopper to feed fuel to the cooker, I load mine once with the basket with about 20lbs and get anywhere from 18 to 25 hours burn time and still have to let it burn its self out before leaving a comp. I haven't been using water lately and like the results, so you have that option. Just remember one word, LEARNING CURVE, ok thats two words. what ever you get is going to be a great experience for you no doubt .
