quick change vs 9in

[mod33]

I know the big difference but if you don't change gears that often is it really worth getting a quick change? Do they differ in width such as a 60 in quich change is same as 60 in 9in? Any help would be great
thanks

If your not changing gears more than 2 times a week than stay with the 9 inch(less rotating wt) you can get a QC in any width and offset just change tubes out and get the rigt axles.
