Which sup should I buy?

Hi! I’m from Ischia (Italy) and I would like to buy a new SUP. I'm a beginner and I think I'll use it at sea. I searched up something about the different kinds of it, I learned that the best measures are up to 3mtx80cmx15cm. I’m undecided between the brands Huiike, Aquaplus, Hitabay and FBsport, I found all them in Amazon. Can you recommend me something? (I would like to spend €160-180)
