I came across a reference to using the DIGU setting for JT65A, but there was no discussion as to why this might be better/worse than USB. Not knowing otherwise, my Flex has been set to USB mode with a filter width of 2.7 kHz.

Much like any other audio input to an SSB transmitter JT65 can generate a poor signal if over driven. PSK31 (USB and LSB both supported), and two user-defined modes (for SSTV, etc. Avoid ALC action if possible with an AFSK signal. They are perfect for operating PSK31, FT8, JT9, JT65, Echolink and any. It uses AFSK and this is a critical distinction.

USB is the standard sideband used to generate a JT65 or JT9 digital signal. Note that the selected sideband was referred to as the 'exalted' sideband. G2A Phone operating procedures USB/LSB conventions procedural signals. I like the graph showing opposite sideband rejection with the Sideband Slicer.

Note that they were selling Central Electronics phasing rigs right next to the ad for the Collins filters. No wonder the phasing method was so popular. That is the 1954 equivalent of $566 dollars today. And the ad seems to focus on the 75 meter band which was seen as the most important phone band at that time.Дale was selling Collins mechanical filters for 55 dollars. But the assumption here was that hams could use USB or LSB - no rigid adherence to the USB/LSB convention. I think this assumes really great opposite sideband rejection in the transmitters, and excellent selectivity in the receivers. Note that Dale was so intent on selling SSB gear that they were willing to make on-the-air schedules to demonstrate SSB superiority.Дale claims that with SSB you could have TWO roundtable QSOs on the same frequency, with one group on USB and the other on LSB. It provides an interesting view of where phone operations were in that year. K9YA Telegraph ran (on Facebook) this ad from 1954.
