That is a loaded question. "Best" is very subjective..
What are you looking for specifically in polish? There really isn't a best for color in terms of polish. What polish/pad combo one person may decide to use would really be based on current paint condition and what it would take to provide the desired level of correction.
If you're looking for the following answer: m105/m205 is best for white, menzerna SIP is best for black, etc.; it doesn't work that way.
In terms of sealant and wax? What are you looking for? Bullet 1 of this thread
is a good reference. Once you decide what you want most from the criteria, post that and then folks can give you a better recommendation.
