Sporting Clays the distance to the target when shot varies from very close to far. You can use the appropriate choke for each presentation with an O/U.
I suggest you simplify it by choking for close Cyl or Skeet, not so close Lt Mod or Mod and Far Lt Full or Full.
Simpler: IC, Mod or Full.

Getting back to your original question try and hold and swing each model. I believe each has a different forearm. Also maybe slightly different stock.
Even shooting more SC than Trap, if the Trap gun has a parallel comb I would get that. Of course if the sporting model has an adjustable comb you can make it parallel or close to it. The model you showed looks more like a trap gun except for the stock.
