Which is better wood or steel beam?

I'm just curious, could you help me understand the differences between wood and steel beams? Which one would you recommend for a construction project, and why? Is wood more environmentally friendly than steel? Or does steel offer better structural integrity? I've heard about the cost differences, but how significant are they really? And what about durability? Which material is more likely to last longer? I'm trying to make an informed decision, so your insights would be greatly appreciated.
