Interesting recommendation. A number of websites claim an AGM is an "upgrade" over an EFB and entirely appropriate if additional power and life is needed.

Yuasa states:
Q. What are the differences between EFB and AGM batteries?
A. EFB batteries have been introduced as a lower tier option to AGM batteries in terms of performance and durability. EFB technology relies on improvements to existing flooded technology through the addition of Carbon additives in the plate manufacturing process. AGM batteries benefit from the inclusion of unique design features not found in wet-flooded batteries. These include glass mat separators, recombinant lid technology and higher pack pressures to facilitate improved cyclic lifespan. AGM batteries are better suited to meeting the demands of higher specification vehicles that include one or more of the following technologies: Start Stop, Regenerative Braking and Passive Boost.
Yet this manufacturer says their research shows EFB to be the preferred technology over AGM.
While AGM batteries have handled the demands of modern automobiles, EFB technology surpasses AGM in critical areas such as battery life and heat tolerance.
