Open-back headphones when in the booth, but not recording?

I have been using some pretty cheap gaming headphones in my booth for a while now, and I think it is time to upgrade. I also edit from my booth since I don't really have a better place to do it. I was thinking of getting some nice close-back headphones, like the Beyerdynamic DT 770 pros. They are great for not leaking noise when recording like open-back headphones would.

But, this got me thinking. During the process of mixing and editing, most audio engineers recommend open-back headphones as they tend to be more accurate. Maybe I should just get a set of open-back Beyerdynamic DT 990 pros, or the newer DT 900 Pro x, since I can just wear my old headphones during the recording process. I don't think it matter how accurate the frequency response of my cheap gaming headphones are when I'm recording. It really only important when editing and mixing, and I can just switch over to the new ones for that.

Anyone have a similar set up? Does it work for you? Thanks.
