Canson are certainly not the only nice/popular papers- many users (including us) also really love our Type 2 and Type 5 papers (Type 5 is our and many users favorite glossy paper), as well as Epson Hot Press papers, there are some very nice Moab and Hahnemuhle papers, and more people are printing on Japanese papers, such as Kozo, Mitsumata, Unryu and others. All papers will give different results, depending on the base paper color, texture, and coating (or no coating).
When people are searching for the right paper(s), we recommend they get sample packs from different companies to see, feel, and try different papers to decide which they like best. You can get sample packs of JonCone Studio, Canson, Hahnemuhle, Moab, and Hiromi (Japanese) to try. I have made two fat 3-ring binders of test prints (with both ConeColor and Piezography inks) and information of different papers from many different companies, so when people come to our studio, they can really see how different papers look and feel- which is very helpful for them to decide which paper(s) to use for their specific printing project.
