Is the Optima Blue Top Strictly for Marine and RV use?

I was able to find a deal on The Optima Red top, only to find out that they were all sold out. I was offered the same pricing on a Blue top. The Blue top is a deep cycle battery, whereas the Red top is not.
Is the Blue top essentially a yellow top battery that is sealed for marine use?

Is it worth consideration, or should I just spend on a Yellow Top battery?

thanks!

 

The yellow and blue are the same battery with differant terminals. The blue has binding posts and screw posts and the yellow top has threaded holes. Both will start a car just fine I used a group 31 blue top foe years to start my car and it was fine

 

blue tops are a really good battery for its cost range.
