20" or 21" tires

My order is going to be placed on Tuesday for a 2017 XC90 inscription model. Will I get any better ride handling with the optional 21" tire/Wheels ? is their any advantage going to the larger size ?
Its all for looks, plus the ride will be a little stiffer due to the thinner tires.
I think 21" will be slightly better handling (NOT comfort). Is it noticeable. Probably not.
