Final Cut Pro doesn't let me change H.264 Faster Encode to Better Quality

In the past I have used "Better Quality" setting over "Faster" thinking that it relates to image quality.

But maybe "Faster" now really means faster hardware encoding via GPU ot T2 chip and "Better Quality" means slower CPU encoding? And to clear some confusion Apple has now removed that "Better Quality" setting so people don' use it to no effect??

The link below discusses Compressor but AFAIR I recently read a similar test about Mac mini 2018 T2 chip and FCP encoding settings.

"To enable hardware acceleration, be sure to select Faster for the Encoding type in the Video Inspector. Setting the Encoder type to Slower performs compression using software, which is much, much, much slower."

It’s been changed in 10.6. It may have been intentional or it may be a mistake . For most material the difference better Faster and Better is not discernible.
