The first (Marine Master) is clearly a starting battery, and says so. "Marine" might mean it has improved vibration resistance, but the fact that it has nothing to do with deep cycle performance is a good reason to ignore the "marine" term.
The second (EverStart) is also quite clearly labeled as a deep cycle battery. The "start" is just in the brand name, not a surprising choice for a line of batteries! I suspect the warranty has a lot more to do with price than actual construction... like the old Chrysler 7-year warranty, which was them buying a belief that their cars might actually be any good.
The final example (NAPA DP) is also very clearly labeled as a hybrid or compromise. Right on the sticker it says (with my addition of bolding for emphasis)
How much more clear can they be?Designed to provide heavy-duty starting power AND moderate deep cycle service
I agree about the choice - look for a straight deep cycle battery, or an AGM dual-purpose (they handle high current so well that it doesn't compromise their deep-cycle ability as much as a flooded-cell design).
