Tip, which newest series do you mean? Shin Tenchi Muyo (the one with the flat-out bizarre animation) or the just recently released OVA 3? Because, typically, STM is the one hated.
Anyway, yeah, if you want the manga look for the old editions - the ones either huge, or the ones with the logo that doesn't say "VIZ media". The ones with the latter have edits to the art and dialogue, something that fans like myself despise.
