Tivo Box versus Virgin TV 360

I've just gotten an email from VM informing me that if I want to continue accessing Netflix, that I need to upgrade to the 360 box, which is free.

Are there any downsides to this?

I know the 360 box supports HDR and 4K, which is great. They can't transfer my recordings or series link settings, but I only have 1 series link set up and all recordings have been watched, so no harm there.

So, any downsides I should be aware of?
