I, myself, thought that I'd be better off with more RAMs instead of a doubled bandwidth. What do you think? Do you have any source to which one is better off ?
Without doing too much research, you're probably right. The difference between dual channel operation and non is significant. However, when performance will really take a nose-dive is when your RAM fills up and your computer is forced to begin swapping data to the hard drive.

So, if your apps are sucking up all available memory, it seems reasonable to assume that more, slower RAM would still be preferable overall to than having faster RAM, but not enough of it. Besides, if I'm following you correctly, you should still have the option of getting a second 1GB stick in the future and going dual channel that way.
