So i used to play standard minecraft many years ago when i was a kid but then i got very burnt out and havent played it sense. Minecraft has a bigger community/mods than minetest, but minetest is a neat little lua project. How do i decide? what would you suggest?
Minecraft is substantially farther along in terms of gameplay, mechanics, details, etc. than Luanti. You will probably have more fun playing Minecraft.
That being said, Luanti is free and also pretty fun.
So my advice is if you only want to play one, play Minecraft. But if you want to, play both.
