It's gonna come down to how well Edgar deals with the body shots that Holloway just loves to dish out. If Frankie can't find a way to stop or counter them he's going to have his gas tank sucked dry like every other one of Max's victims, and from there it's all downhill. I think most of Frankie's wrestling will be neutralized by Holloway's distance control, you can't get a takedown on him if you can't get the position to shoot one and Holloway doesn't make that easy.
I love Holloway's body shots. I've been a big fan since his second fight in the UFC because of those body shots, and if Frankie isn't scoring frequent takedowns they're going to be a problem for him. With Max's chin and Frankie's at-best-okay power, I think scoring enough takedowns where he doesn't take too many of them is his best route to countering them, and probably his only route.
I'm not convinced Holloway's distance control is that much of a problem for Frankie, who excels in wrestling transitions. If we were discussing Holloway against Mendes, I'd agree. Mendes has a great entry, but isn't a great chain wrestler. Frankie's the opposite. Frankie can blow an entry, but unless Holloway gets out of there real quick, that entry is just a way to close to distance. I'm a big believer in Holloway—a big believer in both these guys really—but he hasn't actually demonstrated that ability against anyone anything like Edgar.
Aldo literally worked over Frankie in their last fight. So we know Frankie isn't the best, he's lost to Aldo twice now and the second time was a beating.
You make some valid points, but this isn't one of them. Aldo outstruck Edgar 80-79 in significant strikes in their second fight, winning the scorecards 49-46 x 2 and 48-47. It wasn't as close as their first fight, certainly not close enough to dispute the decision, but it was a close fight. Edgar losing two close fights to a 10-year undefeated guy that matches up very well against him doesn't mean he's not the best. Styles make fights. He may still the best overall. If Holloway beats him, then we know for sure. If Edgar wins, it's harder to say, since Edgar arguably matches up well against Holloway.
I favor Holloway because I think he's still getting better and Frankie has started to slowly get worse, but this is an amazing fight between two guys who may both be among the 5 best p4p fighters in the entire sport, let alone best in the division. I just wish it were 10 rounds, because they both have the ability to go that long. I think Max has the best resume right now, but the Edgar fight is one—the one—he needs to prove that it's more than just on paper.
