I currently have one X60 (V2) as my main device and three additional X55's in my network.  The official documentation suggests this is the correct setup with the X60 taking precedance over the X55s as the main device (I assume due to the better hardware).

However, I am wondering if there is any benefit to making one of the X55s the main device due to the continued support and new features coming to these models and not to the V2 X60.  I know there is the homecare vs homeshield debate, but would it be worth it for extra features such as whitelisting and Matter etc?  Would there be any performance degredation or any other downsides of using the X55 as main?  Or any other advice on this would be appreciated.
