rodenstock sironar digital 55 lens or Hassel HC 50 lens

[studio347]

Hi,
I want to hear some experiences with these lens_ rodenstock sironar digital 55 lens and Hassel HC 50 V1 lens.
I want to get one of these lens for still life shooting.
Obviously, they are different. I use both sinar 4 by 5 and Hassel H2. But in terms of image quality, are they similar?
My usual lens is schneider 100 mm digitar with p65. Are both lens good enough compared with the 100 mm lens?
Is any lens better than the other when shooting still life(from 2 to 10 feet @ F11 or F8 with p65) in terms of image quality?
Thanks in advance!!
