Honestly IE on WP8 is a great experience so I haven't felt the need to look but no, all browsers use IE on the phone. And for me the key feature is everything just works. Theres no need or feeling that I need to flash a rom (which I felt I has to do endlessly on Android). The integration with the ecosystem is nice, sure it's missing some core features iOS and Android have after years of beating MS to the market but hopefully it'll show up. The major thing its missing is device integration, my fitbit not syncing saddens me everyday and theres not much I can do about it.
