As a practical matter, niether will fail.
The rope will chafe somewhere first. More likely, the rope was sized for "hand" than strength, so again any difference is unimportant.
One reason you sometimes see seizings instead of splices is difficulty in splicing old rope.
The major downside of a seized eye, in my expereince, is vulnerability to UV damage, since the seizing twine is small diameter and exposed.
A practical advantage of a seized eye (or a knot) is that it does not stiffen the rope due to tail bury and thus can be placed closer to a block (the tail of a splice doesn't go through blocks well). A compact knot can be even better and will allow for easier line end-for-end swaps.
