I’d argue Java, but the edition wars may soon be over, as Minecraft Java and Bedrock editions are no longer available to purchase separately on PC.
Now, for PC players in particular, there will only be one version of Minecraft available for players; this version, called Minecraft Java and Bedrock Edition, will require a single purchase and is “the standard and only offering of vanilla Minecraft on Windows PC.
Most, if not all of us, will have some sort of preference when it comes to Minecraft editions.
