There is no gasket better than its installation. First and above all, flat surfaces required, along with cleanliness. Rigid castings are better than stamped steel pieces. Then, proper torque... and never over-torque, especially with rubber type gaskets as rubber does not compress.. it distorts... too much squeeze and it splits. Cork-rubber and fiber type gaskets will compress. Also, never apply or spread RTV silicone all across a rubber gasket... it will act as a lubricant and welcome the gasket to split or slide out of position; rubber gaskets always best installed DRY.

Read the instructions that should (hopefully) be included within manufacturers gasket sets.
