So, make sure your car's paint is in good condition - this will require polishing and (maybe) compounding. Afterwards, any product would look good - heck, I've seen some good-looking posts on other detailing forums using Turtle Wax Hard Shell. Conversely, the most expensive Zymol or Swissvax wax will not make swirly, cloudy, scratched paint look good.
Also, just to define terms (as commonly used - note some companies use them differently) - a polish is a product that is used to level/abrade the paint, in order to remove swirls and scratches. A wax (or sealant) is a product used to protect the paint, preventing contamination from sticking and preventing UV damage to the clear coat. So these serve two different purposes. Sure, there are products that do both (usually called all-in-ones or cleaner waxes/sealants), but as with all things, it is (generally) better to use products made for specific purposes, rather than jack-of-all trade products.
