Are Optima batteries still worth the premium price?

This is the most contested question in the data. Long-time Optima owners on r/overlanding and r/CarAV report 10+ year service lives, while more recent threads on r/cars, r/SN95Mustang, and r/MechanicAdvice describe batteries failing within 1–2 years and inconsistent warranty experiences. The consensus is that Optima still has real vibration-resistance and deep-cycle advantages, but build quality has reportedly slipped since the brand changed hands.
