Anyone Use the AX4200 Satellites with the AX6000 Router?

I have the RBK853 AX6000 Orbi Wifi 6 system, but have been considering getting a few more satellites for media centers that are otherwise still streaming on wifi in the house as they do better hard-wired to the orbi satellites to take advantage of the Wifi 6 backhaul.  

Technically Netgear says RBS750 satellites AX4200 are compatible with "Orbi Wifi 6 systems" but has anyone used them with the AX6000 router?  I've had too many unpleasant surprises with Netgear, and the price point of getting a 3 pack with 2 satellites for $550 seems worth more than getting a RBS850 standalone for $379, or a RBS750 standalone for $279

Appreciate anyone thoughts, technically I think they just have a slower processor and less an eternet port but otherwise they should be specced the same
