I use(d) JT9(a) slow, JT65 and FT8 on 6 , 4m and 2m quite a lot and achieved with JT9(a) quite a number of qso's iwhich did not complete in JT65 or FT8.
The actual difference between J9a and JT65 may be even slightly more that the two dB calculated theory: 2dB is a lot at flat VHF conditions .
Each mode has its merrits and its limitations.

According to the WSJT-X User Guide, second paragraph, "JT9 was originally designed for the LF, MF, and lower HF bands. Its submode JT9A is 2 dB more sensitive than JT65 while using less than 10% of the bandwidth.” The User Guide statement is referring to simulations based on an AWGN channel. What’s the basis or context for your assertion?
