I use a 9180 with charge wizard (Original equipment) it's a "Big Brother" to yours.
When I got the RV I did some research into converters,, Now there is no single "Best" converter, there are many however which qualify for the "Best" band (likewise there are many that do not meed that quality) and among the Best there are some that have at least one feature that makes them even better, I call that the OUTSTANDING band, Different makes different fetaures.
the Progressive Dynamics 9200 (or the 9100 with wizard, or for that matter any of the charge wizard controlled models) falls in this "Outstanding" class. It is one of the very best made.
NOTE that there are many in this group too.. But it's in there, none better.
