>>1939261as far as edge retention, 1095 is hypereutectoid, meaning there is more carbon than can be fully dissolved and used to make martensite. Because of that, it will have some carbides in the mix which will increase wear resistance.
>Tougher steels can take much thinner edges without becoming chippy.true, but harder steels can take a finer edge without rolling and needing to resharpen frequently. It's all about use case
The chart you have for 1075 shows 65hrc is achievable but only at very low tempering temperatures. I personally wouldn't feel comfortable with only 200-250F. The toughness gained from tempering increase with temperature and I'm not really aware of any knifemakers tempering below 400F.
Here's a chart for 1095 from Kevin Cashen's site. You can temper up to a "safe" 400F for a decent amount of toughness and still have 62-63hrc along with all those good carbides.
I'm speculating here, but I think OP's claim could be valid because you would have to temper 1095 to a higher temperature to reach the same final hardness as a given piece of 1075, which could mean greater toughness, and it should have higher edge retention from carbides.
All that said, it still is personal preference. Some people like softer steel, and it might be good for a beginner to get used to maintaining their tools and get the hang of sharpening.
And now I'm sad because I spilled my special heat treating oil for 1095/W2
