AJAX Control Toolkit CollapsiblePanelExtenders vs. Jquery?

I have used AJAX Control Toolkit CollapsiblePanelExtenders before. And now I'm debating if JQuery collapsiblepanel that someone had developed is better performance wise.

Also wondering as to the latest verdict on using AJAX Control Toolkit. Is everyone moving away from AJAX Control Toolkit, and going with JQuery? Our apps are using ASP.NET Web Forms .NET 4.5 and seems to have AJAX updatepanels, and only a couple of AJAX control toolkit controls.

Thanks in advance for your help!
