I think it is a better choice than the pro, as it costs the same once you purchase the wrist rests (which the pro comes with).
You can re-macro every key on the board, and the macro stays with the board if you move it to a new computer.
The Edge has everything that was missing from the Pro. It truly is the perfect keyboard, in my opinion: split, backlit, mech switches, fully (and easily) programmable, multiple layouts, internal memory, extra macro keys. What more could one ask from a keyboard...? The only shortcoming is that the keycap profile is custom, so it's hard to pimp if you are into color schemes, but that's it. I don't understand why they chose to market it to gamers, when it's the perfect hacker's tool, but I guess them kids are more willing to splash the cash these days.
After dropping coffee on it for the N-th time, I left it outside to dry. I didn't notice that the location I placed it had direct sunlight - plus, it was during the summer.
One of the spacebar keycaps warped to the point of being unusable. I tried several options (including attempting to 3d print a replacement). Was almost giving up, emailed support.
They sent a replacement keycap, for free. For the Freestyle Edge - the one with the blue backlight, that's discontinued.
I'd say the major drawback that it has is the "gaming" name, which makes it awkward to get your company to expense :)
I'll add another drawback: the switches are not removable either. So if you wanted to replace your switches with different ones (for instance, WASD), you really can't (practically).
