The question depends upon several factors, if you must get to work on time, a reliable starter is essential. If on the other hand, you ride only for pleasure, you have more latitude in getting the tuning perfect for long hot rides. do you enjoy fiddling with the bike, or is it a chore to adjust? The VM carb is labor intensive and will need to be adjusted frequently if weather changes from warm to cold, elevation changes from high to low etc. If you find these adjust ments to be a chore, a CV carb may be a better fit for your needs.
It all depends upon the Zen and the Art of Motorcycle Maintenance.
