NXT is excellent, though it is more of an all in one as it does fill to an extent. It leaves a great gloss, but is down on durability. You could use the Tech wax and top with the carnauba. I have nxt, but have no experience of the other you mention. I have used and have Gold Class liquid wax which is very good. Also the paste variant is quality as well.

 

I've used the NXT tech wax for years, found it to be fantastic and lasts well.
Fills swirls well and iirc it's sealant like too.

 

Thanks for the info everyone!
Based on the gathered information I did some googling and I will apply both waxes to get maximum protection and shine! Thanks everyone!
