Mother's and Meguiars both make great waxes.
Don't buy into the boutique wax hype.
What makes a car look good is the proper paint prep. If you prep the paint well, it doesn't matter what wax you use, even the cheapest turtle wax, it will look good.
In fact, I would even challenge that it would take an expert (i.e. very few people) to be able to differentiate between two cars that have been prepped well and topped with different waxes.
If you want to top Klasse, I would make sure that you are using a non-cleaner wax.
