Depends on what landrace you are thinking about growing some landrace strains produce very little buds, while others produce a lot of bud but it might be weaker or more leafy than bud that's gone through some breeding. I just watched a pretty informative video on YouTube about landrace strains and the hype around them. The overall consensus was they might be fun to grow but most people expect them to be god like plants and they usually get disappointed.
Edit: also should be mentioned that landraces really are effected by environmental conditions, these plants spent 1000s of years in the same environment, and don't like changes, so replicating that environment can sometimes be a struggle
