Teeth Whitening Trays And Gels

which is a better whitening gel for my teeth?

does the brand make a difference on the result of my tray whitening system? I am currently using Brav Premier whitening gel, I am looking into buying more but do not want to go to the dentist.. I can just order it online. I saw this brand Polanight online and was wondering if they make a difference?
