When you shop for seals, gaskets, and o-rings, the real question is rarely "which rubber ring is better?" It is "what are you sealing?" One of these products is built for an engine rebuild; the other is built for the lid of a pressure canner. They only look similar because both are replacement gaskets.
Quick Verdict
If your project is a pressure canner lid, choose the Mirro replacement gasket. If your project is a Can Am engine rebuild, look at the BriSunshine kit. Both are new replacement parts, but they are not competing for the same job.

Product Notes
Engine Piston Gasket Repair Kit Replacement for Traxter
If you are tearing down an engine, this BriSunshine kit puts the crankshaft, cylinder, piston, and gasket in one repair package. It is listed as new, and the compatibility list covers the Can Am Traxter/HD10 along with several 1000 4x and Outlander 1000 variants. The trade-off is bulk. With a listed item weight of 29.65 and dimensions of 21.26 length, 15.75 width, and 8.66 height, this is a substantial kit to handle and ship. It makes sense when you actually need engine internals, not when you want a quick lid or valve seal.
Replacement Gasket for Mirro Pressure Canner, Compatible with 12/16/22QT Models
For canner maintenance, this Mirro-branded gasket is about as direct as a replacement part gets. It is made of food-grade silicone, has a black matte finish, and fits the Mirro pressure canner models M-0512, M-0522, M-0312, M-0406, M-0416, M-0526, and M-0622, including suffix versions like M-0512-11. At about 12.6 inches in diameter, it gives you a clear size reference for the lid. The limitation is that it is a single gasket, not a repair kit. You get the seal itself, so pair it with your canner model before ordering and use it for the lid it was made to fit.
Final Choice by Use Case
Choose the BriSunshine Engine Piston Gasket Repair Kit Replacement for Traxter when you are doing engine work on a compatible Can Am platform and want the full crankshaft-cylinder-piston gasket package in one order. Choose the Replacement Gasket for Mirro Pressure Canner when you own a Mirro 12, 16, or 22 quart pressure canner and simply need the lid to seal again for your next canning session.
