Jeff,
I hesitate to get started on this subject because it can get complicated.
I prefer using the 5511e Blue Sea dual circuit switch in conjunction with any ACR/VSR. There are multiple applications when the switch is needed to manually circumvent the ACR/VSR. It could be for AC shore charging when you want truly isolated battery banks. It could be on a very large audio system with a very large stereo battery bank after a long playtime at rest and as a result the functionality of the ACR/VSR has been exceeded and it won't combine. It could be during for a long weekend at a distant destination where you may be camping and have no access to AC shore power.
You can do many of the same functions with a rewiring of a conventional dual battery switch but the function won't match the switch nomenclature and that would be more than a pain.
A simple On/Off battery switch can facilitate one additional function but can't duplicate the multiple functions of a 5511e.
So there's my vote.
