There's only one real Porsche, a gasoline-engined 911.
(Of course, if a lot of other people share my extremist views, that's pretty bad for Porsche the company. They likely can't survive just producing 911's. Oh well, I'm not here for corporate charity anyway.)
But the 911 range has a lot of bandwidth and there are models that go from minimalist driver’s car (911 T) to Touring/GT (most 911s) to race car for the street (GT2/GT3). But you definitely pay to step outside the GT box.
