My experience of other V Twins, Guzzi is good and absolutely everything else I've owned on bikes is better than the S&S except Harley which is equally as bad. Ducati,BMW (flat twin admittedly) Anything Japanese is far better than the M3W engine including my Honda CX500 which I owned 20 years ago. The S&S engine is American and therefore is underpowered,vibrates alot because it basically belongs in a Tractor and is inherently rubbish, also the finish which looks lovely will deteriorate faster than a whores knicker elastic in European weather. However if you are a car enthusiast then the M3W despite its shortcomings is the best car ever made. Four cylinder engine???, don't think so. :-)
