I've had all three brands at one time or another. My choice is a close race between a Componon S and an EL Nikkor. I currently have a 300mm Componon S that I really like. However, my 150mm El nikkor still seems tops to my eye. Either would serve you fine.
I once had a Rodenstock Rodagon 150mm. After I got the El Nikkor my prints seemed to have alot more snap. Perhaps the El Nikkor is a better design? Somebody here has to know.
