On paper, an Optima Yellow is fine, though the forums are split on whether the quality "went down" when the mfg. was moved to Mexico over 10 or 20 years ago. Odyssey and Northstar are the glamour brands, but many 'other brand' AGM's can be gotten for somewhat less $$.
One note: If you do a lot of short trip driving, AGM batteries may not get a full recharge in normal use.
I live in the city, so a lot of short trip driving. My last Odyssey PC1500/34R was still starting fine when I decommissioned it at about the 6.5 year mark. After I replaced it (with another of the same battery), I learned that all that short trip driving---without being fully recharged--- had reduced it's capacity.
Now, with my new, fresh, miracle jewel-like Odyssey battery, I top off the charge with a smart charger every other week or so.
