The JJ Electronic 12AY7 is a low microphonic tube built in the same rugged fashion as all JJ preamp tubes. This tube offers the classic warm 12AY7 sound with rich and balanced harmonics when pushed enough to break up. It’s a great choice for authentic tweed tones but can also help clean up amps when used in place of a 12AX7. Additionally, the JJ 12AY7 is a great replacement in 6072 microphones.

Good tube, used to drive the reverb tank in a Princeton reverb amp, nice sound and provided a wider range of adjustment

Not horrible. Somewhat good but, a little blah at the same time. YMMV. I don't like to trash talk products. FWIW, I was comparing a NOS 12AX7 so not a totally fair comparison. Low cost, probably pretty hardy, and not terrible. Just pedestrian maybe. They're good to tame an unruly amp.
