My Cobra's Armondo pan doesn't leak a drop. In fact, my 427 doesn't leak at all. (Probably just jinxed myself!)
I do have personal experience with three Canton small block Ford pans that are leakers. Very annoying to fix when you have to pull the engine to fix them.
I recommend pressure testing any
oil pan before putting it on. I'd suggest this on any brand you use. No one is perfect.
