I use both. I find the original design much more comfortable and easier to use for day-to-day use. Taking out an AirPod is much nicer with the original design that just ”hooked”. The new design is a pain since you have to create a seal.
I only use my AirPods Pro when travelling, listening to music, or using motorized equipment like my lawnmower, weed whacked etc.

I can wear the old AirPods all day with no problems. The new ones make my ears sore after an hour or two.
