Minecraft mapping

What in your opinion is the best minecraft version to build with?

Currently, I build on java and am trying to work on my skills which are currently good but can be improvedto hopefully open my own server fully with my own custom builds. What is the best way to work on this?

To upgrade your map to the largest size, you need to upgrade your map from Level 3 to Level 4. Add the Level 3 map and 8 more paper to the 3x3 crafting grid. The newly crafted map will now be upgraded to a Level 4 map which is largest map size in Minecraft.
