I don't recall where this table of Relative Sensitivity of Communication Modes came from but for what's it worth::
I would estimate that FT8 is 6-10 dB better than CW with very good CW operators on both ends. Last I heard from K1JT, JT65 is a few dB better than FT8, and JT9 a few dB better than JT65.
I can quote from this experience on 160M with JT65 and FT8. I'm near San Francisco. For most of the winter of 2016-17, in pursuit of the last three states I needed for QRP 160 WAS, I let JT65 run all night and kept a record of all the stations I decoded. I logged stations from all continents, including a dozen EU stations, and several times a week, VK6IR (about 8,000 miles). I also logged stations from every state except VT (one I needed) and most VE provinces.
This past winter, there was virtually no JT65 activity, replaced by FT8. I heard a lot east coast stations working EU, but I didn't log a single EU station.
