My dad uses helmets with those pro-shade systems and he likes them. I've never used one though. It seems practical. I just spent so much money on this helmet that I don't want to buy another one for a few years so I can mentally justify the purchase.
My dad uses a Nolan helmet like in the picture.
My GT Air has a built in deployable dark shield. I don't really care for it during bright days. The tinted shields are not available in the US (I was told they're not legal) so I ordered one from the UK.
The drop down shield is good for rides that leave in the afternoon to return after dark. If thats the plan I'll put the clear shield on and use the 'built in' but generally, I think they're sub-optimal.
