On SR, we decided that ["X vs. Y" is not a good question](https://softwarerecs.meta.stackexchange.com/a/70/46). Thumbing through the example questions for this site on Area 51, I see a few of them:

> 
> * Do mechanical keyboards have any real advantage over traditional keyboards?
> * DDR3 vs DDR2 -- is either better than the other? If so, why?
> * Help to choose between Nvidia GTX 860M or AMD Raedon R9 M290X for a gaming laptop?
> * Do laser mice have any real advantage over optical ones?
> 
> 
> 

etc.

Are these questions on-topic here?
