I personally like my v-belts more for the nostalgia factor and its history. Some of the best cars ever built in american history used v-belts, and the fastest production car to this day used them, the Hemi powered 1968 Dodge Dart GTS. They are functional just like the serpentine belt is and in all reality, they are easier to maintain. The reason so many people throw v-belts is because half the time the pulleys aren't lined up. My alternator threw a belt for a while, and when I checked the pulleys weren't lined up right. After that was corrected, I never threw a v-belt for the last 3 years the car was running.
And just to make you think, look how the quality of the average car or truck is these days. The quality has gone downhill in turn for more luxury and cost efficiency. IMO, the serpentine pulleys and brackets really dirty up the front of the motor and take away from the simplistic and cleaner look of v-belts. You also don't have to replace tensioners, serpentine belts are expensive, and looks like more things that could break.
