JCI in general is "meh" quality compared to what else is available in the US market.
Optima used to be fantastic back when manufactured by Enersys (Odyssey), inventor of both TPPL and the spiral AGM technology.
Like the old Diehard, ended up only Platinum was any better than others.
Anyway, developing world and remote markets, and those with high import duties, choices of what is available for reasonable pricing get very limited.
Even chinese Full River are probably better value than Optima for true deep cycling use.
