The problem with terms like "best" is that they're meaningless on their own, kind of like meta tags.
What is best? Is what's best for you the same as what's best for me? The best Linux distro for someone who's always used Windows and is trying Linux for the first time probably isn't the same as the best Linux distro for someone who's worked with numerous computer environments and needs to set up a custom server.
What you're really looking for is almost certainly software that does everything you want with the fewest possible downsides.
So, okay, we've established askers need to provide some context for their requests. Tell potential answerers about their experience, needs, environment or other information as appropriate. But once that information is present, why bother saying "best" at all? Is anyone looking for the third-best software package that will do what they want? I sincerely doubt it.
At best (ha, ha), "best" adds no value to a software recommendation request (or any question). At worst, it's a poor substitute for explaining what an asker actually needs.
