My local Sears has the Diehard on sale for $92.00 each with a 1 year warranty and Costco has the Interstate's for $72.00 each also with a 1 year warranty
What size are the DieHards, Group 24 ? Are they true deep-cycle and not marine "dual purpose" ?
The Costco Interstate batteries are GC2, 6V, so you would have to wire them in series while I suspect the DieHards are 12V so they are wired in parallel. You might need different cabling.
While not a perfectly accurate way of comparing 6V to 12V batteries a good quick comparison is check their weight. The main "ingredient" that you are paying for in a battery is LEAD, so the more, and therefore, the more weight, the better !
Personally, I would go with the Costco/interstate batteries.
