Any reason? The reason I ask, is, I've had some issues with the orange rubber caps not sealing well. I primary ferment in 5 gal carboys, so I usually hook up a blowoff tube to the orange cap, and after fermentation slows down, I'll swith to the universal stopper with airlock, just as you have in your 2nd pic.
