New false ceiling or restore and keep old wooden ceiling?

I have a huge 56m2 old wooden ceiling. I am about to replace it with a new false ceiling but now i have severe doubt as to whether that is the right decision. The wooden ceiling is covered with a thick brown paint. The original wood may be pine but im not sure. The wood needs replacing in a few places and there are gaps in between the planks. It will take a lot of money to restore. Is it worth restoring this ceiling (as an original feature of the house) or should I continue to put a false plasterboard ceiling up? I have to decide TODAY!
