Sad is that many use a double cylinder which is actually against code as a work around.
I call that out.

I have never seen a double cylinder on a Pella door.
For this market area,
The higher in home value,
the less need for external security (seems to be what I routinely see).

I’m not sure of the brand of sliders I installed with this type of configuration; but they were metal and not wood. Even though this type of configuration is used and can be properly secured, I personally do not care for this design where the screen is on the inside and the door on the out. I also feel more comfortable with the door on the inside of the frame; to me it’s a more secure application.

But with good security as Joseph has in place either door will work fine.
