I guess it depends on what's meant by the recession, because it can refer to various kinds of things that are decreasing in price. So if it's the Bitcoin's recession, then Bitcoin is definitely not the best investment. However, if we are talking about the global economic recession, I'd say there's a serious threat of fiat crushing, so Bitcoin would probably be my choice. Surely, Bitcoin can drop as well during this time, but it has the habit of recovering eventually, which is not really a treat of the fiat. And if we're talking about something like the World atomic war, then no money can save us, I'd buy some non-spoiling food, weapons, warm clothing, and cures.
So the answer is that it depends on the specific situation.
