I am going to agree, but say something different
1 - Cam 1 will make slightly more power and will still be mellow as mellow can be, but it may not be worth the effort and risk of break in unless you have a bad cam or bad lifters
2 - The Performer Plus cam (2106) is a nice running cam and IMHO, is a sweetheart for someone that wants a cruiser, but the improvements will be even less than cam 1. (I am on the fence on that last statement, I think either cam would be nearly discernible, but the 2016 would be quiet and real easy on valve train)
However, I think that the changes you are making are good, and if the engine is in good order, leave the cam as is for now. If you decide to make more changes, ie headers first, gears second, then consider a cam to match. No need in doing it now. I'd do ceramic coated headers before I put a cam in it
