I find it more interesting than just ask which one is better...
There's a middle ground between "which is better" and a massive questionnaire with over a dozen options for some questions. Also, it's obviously not more interesting if nobody responds, so that has to be factored in.
Anyway, I didn't suggest you should just ask which is better. You can ask the question as a jumping off point for discussion. That's the whole idea: it's a discussion forum!
