I believe it works well for you. For me one of the important parts that got me to consistently write a journal years ago was also switching to the cheapest notebooks I could get.
With something (relatively) expensive I always had that small, subconscious fear that what I have to write in the notebook wasn't worth ruining the page.
One way to avoid this is to buy something like Rhodia that you want to use but is a bit more expensive. Then buy one even more expensive notebook. Now the Rhodia is your cheaper notebook and there is no longer an inhibition to writing in it!
(Yes this actually happened to me)
So in my experience Rhodia (and other "higher-end" perforated) notepads are pretty sturdy and tend not to fall apart even with rougher than usual handling (mine haven't). There is a slight price premium however.
