I don't see how AGM are better, or in any area they out perform lithium. If you have a lot of after market gear a lead acid battery is going to die quicker than lithium. Lots of after market gear is precisely why I chose lithium.

Lead acid tolerates only a couple of deep cycles. Lithium tolerates many more. Lithium can produce many more amp hours than comparative size lead batteries. Lithium retains charge much longer than lead, not requiring maintenance charges that lead does. Lithium can't spill acid. Doesn't require a special charger (as some claim).

I've seen a video of a lithium battery on a bike with the starter turning over continuously for about 60 seconds (the spark plugs were removed for the test). The battery was still turning the starter strongly at the end but he had to stop because the battery leads were melting. You would be lucky to get 10 seconds continuous from a lead acid battery before it died and was beyond recharging.

But I'm not trying to sell lithium (although I think shares in lithium mining are a good investment). I'm just genuinely enthusiastic because I'm bloody impressed with the technology - and perplexed why some (not on this forum) seem intent on misinforming and promoting dying technology. But there is a place for lead acid - those with modest needs its certainly a cheaper alternative.
