Need best recommendations for Nest Cams

I currently have an Orbi Mesh set up.  My 5 Nest cams do not like it at all.  They are constantly dropping out 100+ times a day.  Nest tells me this is due to the Mesh network as the cams need to be connect to 2.4Ghz and the Orbi switches between 5Ghz and 2.4.  So I want to get rid of the Mesh system and was considering the RAX200.  My house is ~ 3500 sqaure feet over 3 floors (this includes the basement).  I have about 30 devices connected generally including 5 Nest cams (indoors and on the exterior of the house),  3 nest thermostats, 8 Nest smoke detectors, etc. 

Thoughts on replacing my current Orbi set up with the RAX200 or another recommendation?  Any help would be much appreciated.

Thank you!
