As pointed out in comments, the most enlightening guidance on asking and answering best / recommendation type questions appears to be one given in Q&A is Hard, Let’s Go Shopping!
...consider the voluminous amount of information you need to even begin properly answering...
Let’s say the question asker provided all that information. Fat chance, I know, but let’s pretend for a moment they did — and we were able to provide the perfect, ideal shopping recommendation to them. Even if that was the case, technology moves so rapidly that the best shopping recommendations will be utterly obsolete within a year! What’s the point of a bunch of labor intensive questions that provide only temporary benefit to a limited (some might say Too Localized) audience? There isn’t any...
... there is a way to ask these questions that avoids the inherent problems with shopping recommendations. For example, let’s say you wanted — as I did — to buy a point-and-shoot camera that takes good low light photos. So we’re going to ask on photo.stackexchange.com, naturally!
Here’s one way to ask:
Q: What’s the best low light point-and-shoot camera?
...Here’s another way to ask:
Q: How do I tell which point-and-shoot cameras take good low light photos?
...The former question provides the path of least resistance: a laundry list of products I can buy without thinking about it too much. But that answer will only be valid for a year at best. The latter question may take some thinking, but its answer will be valid forever … or at least until camera technology somehow shifts beyond lenses and sensors as we know them today. Thus, when it comes to shopping questions, don’t ask us what you should buy — ask us what you need to learn to tell what you should buy...
Applied to your particular case, a more appropriate question could be like like "How do I tell which jquery tooltip plugin <fill in what do you want from it>"
