Our bedroom is quite generously glazed towards the east and south, and we have neither neighboring buildings nor trees, nor additionally curtains or similar inside: 
Darkening is done exclusively with Roma CDL, and at least we have no problems with it. It is of course not completely dark but more than sufficient for undisturbed sleep. The following picture is from yesterday afternoon (the sun was shining outside), but it is only somewhat meaningful because the camera increases the exposure:

The CDL slats close absolutely flush with each other and there are no holes for guide cords or the like. The only light comes in at the sides (between rail and slat) and from below (we have natural aluminum window sills which reflect well accordingly). The horizontal "light stripes" are actually only the reflection of the rear edge of the slats. We have a lot of fixed glazing with rather thin frames and the lower zero position is also not yet correct (I think the blinds could still be lowered about 2 cm). Whether it gets darker with real windows and a deeper zero position, I do not know, but I could imagine it.
We currently do not have wind sensors; even in strong wind I have had no concerns about stability so far. We have had rattling blinds maybe three or four times in the ten months we have now lived in the house. Curiously, only in the bedroom... I suspect this is due to alternating suction versus wind pressure caused by the corner of the house. In the living room, which also has very large window areas, we definitely do not have this problem.
So much for the CDL promotional block ;). Nevertheless: absolutely quiet and absolutely dark will probably only be achieved with roller shutters. In this respect, roller shutters are probably the better option for a purely bedroom. In all other rooms (including children’s rooms), I would always choose blinds – and the CDL are really a nice thing there.
