RT6600ac mesh with a WRX560

[Enquiries]

I have an RT6600ac with 3 MR2200 meshed. Would it be advantageous to replace at least one of the 2200’s with a WRX560? Any advantage or disadvantage other than cost. All 2200’s are currently wireless connected and no backhaul, letting 6600 manage 5mghz-1 and -2 and 2.4.

Thanks for all your great helpful videos!
