Old volkswagen beetle has most of features of new beetle, 4 tires, windshield etc. but it is not same thing.
With netsurf sites like eab.abime.net are rendered correctly, with aweb they are not.
Surfing experience is totally diffrent, because 99% sites are rendered corrcetly with netsurf. There is no point to say that AWeb has most of features of netsurf, because result is totally different.
