Do you think you’ll have any regrets about the nano texture display?

I was torn between nano and regular glass, but opted for the regular glass.

I have the nano-texture display on my M4. At this point, I don't think I can go back to standard glass. For text work, I find there are no downsides. If you work more with color and detailed art, I think that's the only case where you need to put extra thought into it. Otherwise get it

I got the nanotexture on my current work M4 MBP—it doesn't completely eliminate reflected light, but it diffuses it a lot. If I were in a dark room with a light source positioned perfectly to reflect off my screen in my face, I would probably still have trouble with it, but in general I don't need to reposition the screen to avoid glare nearly as much.

I would say it's worth the extra, what, $200 or so? on the price of the M4 MBP. If it were much more expensive, I would be less sure.

It’s often much more than $200 as the base models can be had for huge discounts, like $450 off retail, but the second you check the nano texture option, you lose the discount and you tack on the extra $200. So it’s often closer to $700 in some cases.

No, I love it. I had non-matte glass screens in my MacBooks since 2012 and I didn't realize how much better it is to no longer see lights reflected in there all the time.

I hate to say it but it's totally worth it. Direct sunlight incredible.
