Did anyone swap the wet cell battery to AGM?

And if yes, any issues? How does it hold up?
I'm asking the question, because in the newer BMW's one has to change the programming from a wet cell to AGM and the battery capacity, and also to register the battery. Basically, in the newer cars, when swapping out a battery one part of the equation is to change the charging parameters of the alternator from wet cell to AGM, and also the charging cycle from a an old battery to a new one.

So if one would swap the regular wet cell battery with an AGM, on our cars, how does the AGM battery hold up? Bites the dust sooner, or holds up OK?

Where I live (Canada), doing internet search, it seems that an AGM is more suited for hot to cold temperature changes (winter-summer). I'm due for a new battery, and I'm on the fence, but not sure how reliable an AGM would be in our cars. Also as a note, the newer cars have the start/stop button which is very close how the v8 starts, and BMW also acknowledged the fact that an AGM battery is better suited for these kind of vehicle starts.

Curious to hear some feedback, if any.
