OK.

Quill stems were always a weak design. They eventually will kill the steer tube if the bike is ridden long enough. They do of course have the obvious advantage of easily adjustable height.

I'm not convinced that threadless stems are inherently ugly, though I actually do concede that the vast majority are hideous. That most quill stems looked nice was mostly because of the design sensibility of the times. Certainly there were also some hideous quill stems by the late 80s.
