Lithium batteries are lighter than lead batteries, last longer, no maintenance and can be completely discharged with no harmful affects.
Are there any experts on the forum that can give an informed opinion? Do they have more capacity (AH) and are they worth the money?

They do have more capacity, but to go Lithium you really want a full charging system and not just a drop-in replacement. Otherwise you won't get the full benefit of them, especially over the long term. One of the biggest benefits is the longer cycle life, which mitigates some of the extra cost.
Even taking into account the longer life, the price is still pretty high compared to flooded lead-acid. In return, you get more capacity, slower self-discharge, and the ability to charge much faster.
