Interstates are great but they lack reserve capacity and cca when you get into the large sizes (bigger than grp 27). It becomes an issue for today's efi motors. Mercury requires 1100 cca for their dts race motors now and I'm sure the rest of the efi line isn't far behind.
Die Hard actually has a good affordable battery to fill the new requirements.
