Minecraft PC has infinite world. You can change any game mode and you can get mods. You can heal with hunger bars, and not just ordinary hearts sittin' there not being healed in Easy, Normal or Hard. Minecraft PC has biomes, extreme mountains and hills, plus the very high mountains (almost up to the height limit (256) It's easy to download maps and such stuff.
Here is why people would vote for Minecraft PE.
Minecraft PE has more cool blocks, such as stone cutter. They would think it's an easier version to handle. You can craft easily, it's says the materials you need. People would probably think getting food to heal hearts in Easy mode, is easier than hunger bar! The Nether Castle might be better then the Nether dimension!
