MooTools vs. jQuery vs. ???

[Firefox Wins]

Anyone here speak javascript?

MooTools:
...I miss me some Mootools. I mean no Native JSON support in jQuery? C'mon......

In response to the "Widely adopted" response, we all know OSCommerce is the most "Widely Adopted" shopping cart, and we all know what a pile of shit that is. I'm in no way comparing JQuery to OSCommerce. I'm simply pointing out the faulty of "Widely Adopted" response.

jQuery:
...Larger community means more support, more examples, more good ideas, and more reusable code snippets, which is especially important when you're working on a rare scenario -- more likely someone else has encountered it before.

Secondly, in benchmarks I've seen, jQuery is faster than MooTools.

and MyBB uses?
What is up with that 'Protoplasmic thingy'.  
"Prototype" appears to be a video game and doesn't rank high in Google without the word 'javascript' attached.

Prototype is a JavaScript Framework that aims to ease development of dynamic web applications.

Edit:
So is MyBB "stuck" with Prototype?
Would the coding involved with changing be 'massive'?
It's all 'just Javascript', Prototype must have some strong positives, right?
Is Prototype the AOL of javascript frameworks?
