Was it the same brand on the two sets?
I'm on my fourth round of tires and would say that there is more difference between brand and model than between 55-profile and 60-profile.
Michelin Energy Saver 205/60-16 were originally fitted, noisy and bumpy.
The first winter I drove on 205/55R16 Bridgestone Blizzak LM, soft and quiet, unfortunately the error reading on the speedometer was a lot, almost an inch difference in height between them.
Changed second winter season to 205/60R16 Hankook Winter icept Evo2 - they were quieter than the Blizzak 55 tires.
The second summer, I had changed the original tires to South Korean 205/60R16 Nexen N blue S, which run significantly smoother than the Michelin Energy Saver in the same profile.
Then I think you should stick to the tire dimension the car had from the beginning, the fact that the 2020EV got a 60 profile is because it was slightly heavier and the 55 profile tires that were on the 2017-2019EV:s have a lower Tire Load Index and are probably at the limit of their load capacity.
In Europe, we have a statutory classification on tires that ranks rolling resistance, wet grip and noise level.
Unfortunately, harder (and thus noisier) tires roll more efficiently, so it is difficult to find a tire that is both economical and comfortable.
Some new tires are harder and have 25% less tread depth from the start just to be able to show good values, unfortunately they are usually more uncomfortable, maybe the ones you got last time was victims for this.
