I have collected several of each type, and use them regularly. They are two of my favourite razors.
I have managed to get ones with only faint cracks in the handle, and some of the single rings do not have any cracks.
Both are excellent shavers (face and head), it would be hard to pick one over the other, however if I need to I would select the Old type.
I find the Old type slightly easier to maneuver as it has a slightly thinner profile.
Agreed. I love my NEW's, but I get slightly better shaves with my OT's.
