Shed made of metal or plastic?

I want to get a garden shed for the wheelbarrow, gardening tools, flower pots, etc. The dimensions should be a maximum of 2 x 2 m. I now have a DIY store catalog in front of me and have gathered information. Wooden sheds are almost not available at all and if they are – they cost twice as much as previously stated. Then there is the alternative of metal (polyamide baked enamel steel sheet) or plastic (metal-reinforced HDPE plastic). What is recommended? What are your experiences? The shed will stand under a tree.

Metal. We have the biohort europa. Top solid and functional.
