I used NetFront on my 3855 and ask me why to use the CSS-enable feature with a PPC screen. Yes if the page sticks HTML rules then the pocket ie renders it better than NetFront. BTW most sites are far from good CSS layouts and don't have a mobile version, so if you want visit them completly you must use NetFront.
Example : go to
http://www.nota-bene.org with pie and with netfront and you will see that pie has a better render.
