Just to be clear, you are referring to stitching an eye with line lying on line. Not stiching through a double braid splice, for example.
Any visual reference for the stitching method used?
I am replacing the lines on the tackle used to haul our dinghy. The attach point to the upper block will need to be stitched and seized. It is now.

Re: Pull-testing stitiching and seizings
Used stitching for may years now and have never had one break where the stitching was.
Good post and thanks for sharing

Pull-testing stitiching and seizings
I was bored today, and I happen to have a pull-testing rig from my rock climbing gear design days. I decided to break some things.
The short version is that the sewn eyes were stronger than the line until I got up to Warpspeed, but even then I could have just added a little more stitching. The seized eyes? Not as impressive. It takes a good amount of seizing and the safety factor is far less for something that looks very strong. Seizing over stitching? Very easily stronger than the line and the seizing protects the stitching.
I like splices when they make sense; just yesterday I was making a few spare soft shackles. I like knots when they make sense; just last week I shortened a halyard and topping lift to move wear spots. But once in a while a stitched eye seems to be the answer (older stiff line and no room for a knot).
