undecided

So I'm painting this table to freshen it. I sanded layers of dirt and old paint but was not able to get it back to bare wood. The plan was to paint it one color all over. Now that I am nearly done, I was wondering how it might look to paint the top black instead. Or, to leave the top as is and apply a coat of polyurethane.

Opinions are welcome --- let me know if you have one.
The top looks rough but it is sanded smooth.

Here's a picture of the table as it has looked for the last 20-30 years. It was greener than the walls, but taken alone, it looked fairly gray.
