I have explained my preference numerous times:
The open foot pocket is more comfortable to me.
The fin platform extends further back under the heel giving better support and less ankle and arch fatigue.
The precurved blade provides much better flutter kick thrust.
The blade has more snap to the tip and a more lively feel.
The bungee straps are more comfortable.
I get more speed and power overall.
I like the way they back up.
Lighter weight, slightly larger blade area, slightly more buoyant.
You have your opinions and I have mine. Different people with different experiences can have equally valid conclusions.
I am not selling my Eddy Flippers, when I need a a fin that frog kicks well, it is my choice. The Go-Sport is just a better all rounder and again, that is my opinion based on my uses and experiences with the three different fins. I accept your opinion and preference as valid for you and I am not going to change mine.
Edit to add, I did leave out one important thing, the Go-Sport is Scubapro and the Eddy Flipper is not
