It's not all about the shape, mostly about material. That's why the F-22 looks more like a regular jet than the F-117. They realized it wasn't neccessary to make a plane look like a 1980's flight sim model.
Not to mention the Typhoon's gigantic tail fin that is totally verticle is a huge reflector of radar beams. Also the other big enemy is the jet intake, which looks gigantic from the front on a Typhoon.
But how do you beat an airplane you cannot reliably get a target lock on?
