New FLO Disc/90 or 2013 Zipp Disc/808

Looking to get an opinion from the group.

I currently own a 2013 Zipp 808 Front and a 2011 Zipp Disc (10 speed that can’t be upgraded to 11 speed)

I have an 11 speed bike that I use the Zipp disc on with a monobloc and I’ve also modified some cassettes to work as well. Overall I’m happy with the set but they are getting long in the tooth and both wheels are due for some maintenance.

My question for the group is this: Would a FLO Disc rear and 90 in the front be faster? The same? I can basically sell the Zipp wheel combo and fund a new set of FLOS…
