Single Stock (JPM) vs ETF (VFH)?

At the moment I’m solely in VFH, but looking at whether I should add some additional positions in arguably the top financial company right now - JPMorgan. What do you guys think?

Advantages of VFH are greater diversification, but if we did hit a rough pullback or recession across the sector, I think have more money in the blue chip stock would be a safer bet than spread among its weaker competitors.
