Seth's better equipped because he's simply better. Braun, with all due respect isn't that great a performer. He's not great on the mic and he's not great in the ring. The only reason Braun is a star is because he's protected as he is. They hide his short comings by having him squash people and performing feats of strength. Seth conversely gets over by arguably being the best hardest working in-ring performer on the RAW brand.
Braun frankly is smoke and mirrors, while Seth is simply a very very talented pro-wrestler. On the mic, Seth isn't great (though better than Braun), but he's at least passable. But in the ring, you can argue he's the best worker on the main roster at the moment.
