Now, this is my opinion only Glen, but being a W123 guy, I just enjoy the round insect looking headlights on our cars. Gives them a personality that is lost a little with the Euro style. The Euro's look good, and even have a certain coolness factor, but I believe something is just lost on the W123's without the rounds....
I think Euros on the W116's and the W126's look much better.
Weird point of view, but just thought I'd throw it out there. You can get H4's that are round.......
