3d printing what filament is strongest?

Very new to 3d printing & im looking to buy my 1st printer ever. Id like to avoid the trial and error as much as possible. I’m interested in a printer that can print something close to peek strength..something that would be close to metal in strength and durability. I’m so green to the subject so my bad for the lack of knowledge but gotta start somewhere. Any help in simple terms would be greatly appreciated
