Dont take this the wrong way, not challenging you over your opinion just want to find out why you feel that way?
You are in a profession that would see a few batteries so your opinion would be worth listening to.
I have chosen to use a red top optima because it is light, having swapped the position of the start and acc batteries the ARB holder was not rated f or the weight of my acc battery, while it was ok for a few years on bitumen i rearranged it before starting my annual desert trips.
Used another type of AGM for a couple of years but it got a bit sluggish at 0 degrees so didnt want to push my luck, the optima has been in for about 12 months now and running a standard type alternator that normally settles down to about 13.7 volts after a cold charge rate of 14.1ish. Still seems to be handling the fresh mornings ok but it was slightly better when it was new.
