ᐅ Garden shed made of metal or plastic?

I want to get a garden shed for tools like a wheelbarrow, gardening equipment, flower pots, and so on. The maximum size should be 2 x 2 m (6.6 x 6.6 ft).

I have a home improvement store catalog in front of me and have gathered some information.

Wooden sheds are almost not available at all, and if they are, they cost twice as much as previously quoted.

Then there are alternatives made of metal (steel sheet with baked-on polyamide paint) or plastic (metal-reinforced HDPE plastic). What would you recommend? What are your experiences? The shed will be placed under a tree.

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