Hi BFL13,
Regular AGM are a "starved acid" design.
Telecom jars are a "surplus acid" design. That means they act in a manner some what slanted towards a flooded jar. I expect the telecom units have some what higher internal resistance.
I got mine because "the price was right" i.e. I could afford to buy them. They are meeting my needs. I would love to go "firefly".

PT, what is a "regular" AGM anyway? Why does Mex insist on the 20% minimum recharge when the battery specs say nothing about that--not being Lifelines?)
