We used Ortlieb for both our front and rear panniers and in general we were happy with them. It was very easy and quick to both attach and detach them from the bikes. They also were very good when it came to being waterproof, as long as we closed them properly our stuff never got wet. In terms of size, they had plenty of space in them to fit all of our things. The only issues we had with them were the plastic attachments on the back that connects the bag to your bike. The plastic is quite fragile and a lot of the screws that connect these parts came loose. Also, the screws are a special type which we could not tighten ourselves, so we had to go to a bike shop which had to fix it with different screws. Overall, we were very happy apart from these problems.
