You would probably get a bit better feedback if we knew what color your car is. Although I'm a Zaino Zealot, all of the above are excellent choices. But your best results depend 90%+ on your surface preparation. Zaino sealants are probably the most durable.
At age 68 with 4 cars, 2 of which really show dirt and poor allpication of sealants, my 1977 Black Excalibur Roadster and my 1991 Buick Reatta Convertible, I want a durable sealant which lasts and is easy to clean and maintain. So if I'm going to put in the effort to properly prepare the surface, I'm going to choose Zaino's sealants. But also, use Z-7 carwash, Z-6 &/or Z-8, and Z-CS. I also like the rest of their product line for interior and exterior care including leather, rubber, etc.
Please remember that Zaino's sealants are like Bryl-cream, "A little dab'll do ya." Almost every new Zaino sealant user applies too much. But once you get the surface prep behind you, application and polishing are a breeze.
But the bottom line with all the sealants recommended above is that surface preparation is the key to a great looking finish, not necessarily the product. Zaino is generally considered the most durable of all listed. My cars are cleaned regularily and garaged when not in use.
Good luck and let us all know your choice and your satisfaction with it.
