I have NOT owned both, but I drive both all summer long. I own a 94 PS 205 and my brother owns a 04 SN 206 SE and we swap boats each time out.
I have driven my MC, a 98 MC 190 (once), and an 08 MC 197 (once), a 79 Tique, 99 SN 196, the afore mentioned 206 SE.
They were and are great boats and I would be proud to own each one. All at once would be even better!!
Now to think of it I did drive an early 90's Ski Supreme many years ago. It was a powerful pull as well but I think it has some extra stuff under the hood.
