Well my red Top that was in my Jeep when I bought it took a crap (only 3 yrs old) so I replaced it with this... not to many options with the reverse post set up. I went with this one.
I heard Optimas weren't made as good as they used to be and don't last as long. I have two red tops in my Blazer and are 3.5 years old and still doing good.
