Choice of converter for AGM batteries
I plan on replacing my Trojan T-125's with 3 (or 4) x Lifeline 12v AGM batteries @ 215 A/H for a total of 645 (or 860) A/Hs total. I want to use the 12V batteries since I dry camp 90% of the time and ...

I am firmly in the adjustable voltage manual camp. I keep thinking about how much of a pain in the butt it would be to have to worry about what stage some converter is trying to achieve and considering battery temperature, and how to determine when full actually occurrs, requiring absorption voltage and an ammeter.
Any automatic converter, without temp compensation is going to be outside ideal, quite often.
Spinning a dial after looking at a thermometer and ammeter is so simple and allows me to achieve the perfect absorption voltage, and the perfect float voltage, and it is simple, takes little to no time, offers a level of precise control no automatic source will ever allow.
And those automatic adjustable sources, how many hoops does one have to jump through to actually adjust it. 90 degrees one day and 50 the next, I spend 0.21 seconds spinning a dial.
The whole 'it has to be automatic' mindset regarding every aspect of life, is a sign of human devolution, in my opinion.
You could not pay me to use any automatic charger in my particular usage. It would be a nightmare of trying to trick it into doing its job, where as the adjustable voltage power supply is plug it into AC, adjust voltage to desired area, connect to DC. Watch how many amps flow to achieve desired voltage.
Cold battery, add a bit of voltage, hot battery reduce a bit, gonna suck up 40+ amps for a while, reduce voltage a bit, maybee.
Not going to be around when 0.5% capacity is reached at absorption voltage, then time to full is not a factor, set to float voltage.
My Meanwell rsp-500-15 is PFC too, and has thousands of hours on it, and emits flatulence in parallel with mine own at 'automatic'
