Wax is wax, if it,s 5.00 or 100.00 it's still wax, I will take any wax aginst any special polishing kit and make it look just as nice.
The only time you will notice a big difference is in buffing and polishing compounds but if you don't know what your doing you can mess up a paint job fast. Armorall wax lasts a long time. I could go on about this topic all day.
