Chrome came OEM, so that's what I use. I haven't tried others though. I am a little hesitant to hand over my phone permissions to a third party, for something as potentially dangerous & malicious as www surfing/browsing. Then again I don't use my phone for anything really dangerous. What really scares me about 3rd party apps is when the originating developer sells the App rights to less than honorable developers and with the change, the terms of the usage agreement change behind the scenes without the end user knowing it.
turn it around... Why should I use a different browser app?
