Course the cost is more. Depends on how long you want battery to last if the extra money worth it. But, even then, no garrentee it will last longer.
I would be more concerned about disconnecting and reconnecting the batteries in proper sequence. A spark or jump in voltage can play havoc with computer circuits on car now days. When I replace battery I try to get the highest CCA battery that will fit my car based on size of my battery box and position of the pos and neg terminals. Some time this involves altering the battery hold down bracket. But, that's me.

While I might think the same, I recall reading that tho get greater CCA they need to make the plates thinner so it becomes more likely to suffer physical damage from vibration etc etc etc.
My battery is 6 years old. It still works but, the headlamps dim at idle. It is time to change it before it lets me down.
