Forget LTE, hello CHROME BROWSER, how are you LAG? good today? nexus 4

Is anyone else disappointed that Google Chrome is the default browser in the nexus 4? the AOSP browser was fantastic, i am already seeing reviews about the browser and its lag "oh its not smooth like safari" "its laggy" etc. the better option would have been to offer both browsers until chrome was brought up to par. why not release the aosp browser on the play store? imo dolphin, firefox, boat, maxathon arent as good as the AOSP.
