I have and will use both where needed but i much prefer bank sticks for the versatility of them. I also find them much more stable and secure, especially fishing close in.
With a pod, i find that you are limited on control as all your rod tips will face the same way, regardless of where your're fishing. I have had a pod tip over on me when fishing right close to the margins and when i had a particularly violent take, it pulled the rod and the whole pod went.
Also with bank sticks, i keep my alarms, bobbins ect on them all the time so its always ready to go.
