Hi,
If AGM is your choice then 3 12 volt jars would outperform 2 6 volt units. The chemistry is the same and so is the cycle depth. Wiring should be balanced as method #3 on the smartgauge site.
When I speak of folks who do not have a clue I am talking about you
3 12 volt Group 24 batteries is 210 amp hours
2 GC-2 Six volt batteries are 230, clearly the better performers.
Now if you are talking Group 31's then you are right.
But I have 12 volt jars in the 20 amp hour range lying about here (emergency and portable batteries) so your statement is made with way too little supporting info.
There are many 12 volt "jars" out there, different sizes, epically in AGM.. In the six volt sizes, there are as well, but very few are common with the GC-2 being the most common.. So you are fairly safe assuming a GC-2 (230 amp hour) for six volt.. But I've seen 250 amp hour six volt as well.
