I have both, my spinners are open face, use em for light weightless worms. I have a buddy that I tried to convince to use bait-casters. He said "I can fish all day with my spinning reel and not backlash once, can you say that?"
Once when my Dad and I were drift fishing for Reds in Sabine lake he was using an old Huge Zebco 888 or similar with 20 pound test. He also had a cocahoe minnow threaded on it upside down, and due to the heavy line and not much of it, he could only cast it 20 yards and it would squawk like a seagull when he did. I constantly chided him about that rig. Once i looked back and his rod was pointed straight down under the boat. and he was winching a huge redfish in. I helped him net it and when he had caught his breath he softly said" wheww, good thing I was only using this old upside down plastic minnow and this old woman's reel, no telling how big a fish I might have caught!" He caught two to my one that day!, I never bugged him about his gear again! I miss him!
