I use both. I prefer to use toluene-free Briwax (formerly Briwax 2000), because I am concerned that toluene in the original formula might eat wood finishes. If I remember correctly, Briwax is a mixture of beeswax and carnauba wax. Renaissance wax is a petroleum-based product. I think Renaissance wax is less likely to show fingerprints, if that matters. Both can be tinted with artist's oils, but Briwax can be purchased in various tints right off the shelf. Hope this helps.
