Thanks for the responses:
cowboy1864, you asked:
"How would you compare recoil between the P30L and the G23?"
The P30L had less recoil "effect" because it fits my hand better. I haven't changed the grips yet (the P30L came with different grip adjustments/attachments). The G23 is comfortable in my hand, but the P30L was very comfortable. I like a bigger/larger grip, so the P30L has that for me.
