All it takes is a little adaptability to make the chisel edge work. But it'll honestly never perform better than a thin, conventional edge, no matter how used to it you get.
This isn't a bad thing at all. Only objective. Just understand your expectations and know the knife's limits. Be aware.

My main carry is a 7A. But I'll be the first to tell you it's not the best knife for cutting. The crooked edge takes getting used too, and regardless of how small the angle is, its still on a really thick blade. Hard to index and steer. My Tenacious honestly outperforms my 7A in every way I've tested, except for edge holding, which is actually pretty close.
But, I will say I've learned to appreciate the chisel grind, mostly because of the uniqueness of it. Really isn't that different to sharpen in practice. Just sounds different on paper. If anything it's actually more finicky, because you can't really hone it well due to not working well with the slight microbevel produced by quick honing. Burr removal is also not as straightforward as described. You still have to work each side like a standard edge to get that soft thing off there. Lotta metal to remove on those thick edges to get anything done.
I won't rationalize how chisel edges are better or even equal, but they are sure different! Bring the option of having that edge ground on whatever side you prefer and NOW we can talk enhanced capabilities!
I guess if I had to really tell someone why I PERSONALLY carry Emerson (ya I know, there's another thread for that), it wouldn't be the chisel grind, or even toughness or capability. There are PLENTY of knives out there that can do everything better. I carry for the style, construction, ergos, and exclusivity. Plus the 7 is an icon.
By exclusivity I'm referring to carrying a knife that's so quirky it actually takes its own skill set to use (just give a non knife person an Emerson and see what I mean 😐

. That's kinda neat to me for some dumb reason.
Overall, I just like Emersons. And have come to like the chisel edge through submission!
As Rolf said, get that 7. I would personally go with the 7A style blade, since it's a little more conventional and V ground.
Enjoy.
