Need help determining best product: Adding Cellular

We currently own a B one router connected to Starlink.

The goal is to have cellular fail-over connectivity.
There appears to be a USB-C cellular product by Peplink.
Another option is to simply purchase a B one 5G router and replace the existing B one.

Does the B one 5G offer better integrated cellular with increased performance over adding a USB-C cellular Peplink product?

(I have more questions to help us decide on which path to go but figured it is best to get this answered first)

How close do you want to connect the 5g module?
There is a max adapter with ethernet that you could place further away.
There is a 5g dongle you could connect with usb c.
Happy to help you though this ,bonding and other questions you have.
As a peplink partner we could send you a quote for either.
