Garage roof concrete or wood - experiences

Hello,
I am facing the decision whether the garage (flat roof) should have a concrete ceiling or a wooden ceiling. The architect said both are fine and usual, it would be a matter of "taste".

Since we are doing the walls ourselves - we would be more flexible with wood, with concrete we would depend on the delivery date for the concrete ceilings of the ground floor and might have to work a bit harder to finish the ground floor on time.

Where do the differences become noticeable? Durability, structural engineering, processing or something else?

What is cheaper? For concrete we were charged 1550 euros for the ceiling panels.
What could a wooden ceiling cost?

Thank you very much for the information!

Hello,

I chose a wooden roof, I always had problems with leaking rain on my old concrete roof (really ancient), and the wooden roof is also much more attractive in my opinion...

I thought the beams aren't really visible from the outside?
There are still wooden slats, some kind of screed, and a tar layer on top or something like that...
From the outside, I've been told, you can't see the difference at all.

It's only the supporting base, either concrete slabs or wooden beams..
