I am in the similar situation like you, and I believe a lot of others as well...
I ride 90% of time in city in various road conditions. For a last 2,5 years I ride my trusty msx 84V. I had for a brief time opportunity to ride S16pro and really wanted to sell msx, but no one wanted it. From my experience, S16pro has much more high (45+ kmh) speed stability and acceleration. S16 is a nimble wheel and has much to offer for the money.
MSX is more fun, more zippy, better breaking, and better range... with 10kg less than S16, which are (next to the fact that I had imidiate buyer ) reasons I decided to sell S16.
I also tried V14 briefly, and it felt similar like S16 with low speed ride, but it is much more powerfull, heavier and can go faster!
18xl V2 at the moment, is a only new wheel which tick the most boxes for me.
