The newer Renogy's are the best value for the money.  You gain all of the benefits of the VSR (plus added intelligence), solar MPPT charger, reduced current, to lower the load on your alternator, and safer battery charge-rate (extending the life of the batteries).  You also buy yourself a bit of future-proofing if you prefer to change battery chemistries in the future.  All for only $100 (or so) more than a VSR or Isolator.

Could you please provide a product link to Renogy's new product that you mentioned, which is about $100 higher cost than the Blue Sea mentioned above?

I searched but didn't find any intelligent charger/separator rated over 100 amps. Below are several of Renogy's products that I found. The ones that have intelligent features is 100 amps (or less),
and the ones rated over 100 amps seem to be just traditional/regular separators.
