It's a subjective question whether blinds are better than curtains or drapes, but I'm curious about some aspects of this.
1. Fire resistance
I'd think that blinds would be more fire resistant than curtains or drapes. I don't know there are fire resistance standards for the manufacture of any of those window treatments. Some drapes feel like they have a coating of something on them, but it might just be starch.
2. Insulation value.
I'd think that, when closed, drapes and blinds would offer about the same insulation value. Curtains would come in third. I supose all of them wiould benefit from having a pelmet.
3. Convenience of adjustment
To me, curtains win, hands down. It's much more convenient just to grab a curtain and pull it open or closed that to hunt for the drapery cords or remember which set of cords raise the blinds and which set opens them.
4. Clean-ability
Curtains are easy to wash. Most modern drapes can be washed but they don't look crisp unless you iron them afterward. Blinds are a nuisance to cleen in-place, but the fair comparison woudl be how easily they would be to clean if you took them down and hosed them off. I've never done that.
5. Pet-resistance. Drapes and curtains aren't very resistant to cats who want to get them out of the way to look out the window. I don't care if they are pushed out of the way, but they get holes clawed in them and they collect a lot of cat hair. I haven't tried binds in this context yet.
