Objectively better

Underground houses are simply better!

oak house with cobbles floor and roof, also lowest block of wall cobble

Personally I prefer an oak floor and cobblestone walls and roof.

Stripped oak/birch walls with oak planks, cobble/plank/gravel floor, Brick for roof or Acacia as an effective substitute, build roof slanted in an upside-down V shape with half blocks with the overhang being a full block tall so it doesn't look weird.

The ultimate quick house recipe.

I prefer smelting the cobblestone and making a stone box house

I make a 10x10 two storie coblestone house with my friend
