Hello! I think they’re both roughly in the same tier so it’s going to come down to subjective preferences…and I personally slightly prefer the sound of the G Pro. I think it’ll be a little closer to what you’re used to out of the A40, too.
It’s funny because Astro is now a Logitech company, so with the Logitech, in a roundabout sort of way…you’ll still be within the Astro family haha. Or at least nearby.
