Frequent loss of connection with Sky Max Hub but no issue when reverting to original Sky router

[Chris280]

I "upgraded" to the Sky Max Hub several months ago and have encountered loss of connectivity between my Sky Q box (and other devices) and the hub several times per day. I've followed all advice including device resets, reconnecting everything in order via WPS and so on. 
Today I decided to switch back to my original Sky hub and, after a quick update of the SSID in the router admin panel, I am experiencing zero connectivity issues. 

Does this seem like a faulty Sky Max Hub or am I essentially paying a premium for a worse solution?

Thanks @Tom-W19 

So after several hours yesterday and more time this morning I'm no closer to a resolution and an Engineer has been booked for the 19th. 

It does seem a lot of messing about when I explianed that I had zero issues with my old hub and now that I've "upgraded" to the Max hub I can no longer use the mini box as this causes the connection to the main box to drop and, even when i do have a connection, the wifi strength across all my devices is so much worse than before. 
An engineer, additional boosters, a potential mini box replacement (all of which have been mentioned by the team in chat) seems pretty unnecessary to me when all i really want is to do get rid of the "upgrade" and just use what i had before - which was totally fine. 
Is it a case of needing to jump through the hoops so that when the engineer inevitably tells me that the max hub isn't really compatible with Sky Q, mini boxes and bossters, I have to start this all over again?
