Usually that's addressed through the quality and heat renage of the plug. A poorly made plug may not transfer energy well, or periodically misfire. Too hot or cold of a heat range can generate issues. The plug also needs to effectively handle the energy provided through our RC ignitions. Since you mentioned the Brison 3.2 you might like to know that particular engine, being Sachs based, is extremely tolerant of plug differences for numerous reasons. One is clyinder cooling area and another is compression ratio. The RCJ7Y is as good as any other plug on the market for that engine.

If a plug fits the reach and doesn't stray too far from the median heat range they will do fine. The better name brands typically provide the most consistent performance.
