It really comes down to preference. It all affects the handfeel of the cube, and some take longer to break in. Maru is really not a long-term lube you can set up a puzzle with, I just use it before comps as it smooths everything out. Traxxas is great for the core once you break it in, but for the pieces you need a lighter lubricant, you could try Lubicle speedy (more high end) or cubicle weight 1/2. People also have success with custom store lubricants like CubeDepot lube or speedcubeshop lube, but the most well known would be cubicle, lubicle, maru, and traxxas.
