I have many different panniers, most ortlieb. Great for touring, grocery shopping, hauling lots of stuff. Very well designed and last a long time.
That being said, we also have 4 Vaude Silk Road trunk bags in our family fleet. I use the medium on the front rack of my off roadish commuter, '92 Bridgestone MB3. We have one large Silk Road that has an insulated bottle holder, no fold out panniers. We have two Silk Road Plus trunk bags that have small, sturdy fold out panniers. Perfect for a tablet or small laptop or the unexpected stop at the grocery store.
The trunk bags get used around town daily. Panniers when needed.
