jQuery vs Zepto, which is better for mobile?

I haven't used Zepto , just read about it . Zepto is more tuned for modern browsers so it is faster than JQuery but one would compromise on the legacy browsers. Infact we use Jquery mainly to support legacy browsers and eliminate the hardcoded javascript for legacy support. So one might conclude for mobile Zepto might be a better option than JQuery and JQuery mobile.

for mobile we can use jQueryMobile instead of jquery, Comparatively Zepto is best because of its light weight

Because its light weight  and comfortable

i can say that jquery, it has spin off jquerymobile easy to write more flexiable controls

j query is better cous there is alot of option in it for mopile
