This is just my own opinion as someone who sews clothes as a hobby, I don't expect anyone else to be persuaded so please don't get offended.
Face masks with seams right up the middle.
May as well wear nothing.
They may look safer, as in a closer fit, but that's just a split that's been sewn up with thread. That will be getting stretched and pulled apart contantly, creating little gaps. Every pin and needle hole in fabric disrupts the weave or knit, weakening the integrity of the fabric and creating tiny holes that don't self heal even if it looks like they have. Tiny mystery holes in tee shirts have usually begun this way.
Is also why clothes usually go at the seams first.
Puncturing the centre of a face mask during construction is a really bad idea and you would be hard pushed to stitch a curve like that without pinning it first, so even more tiny holes.
Seam up the front means it's just a dust mask, a nice looking dust mask but still just a dust mask.
Face coverings need to be a continuous piece of fabric across your wet bits.
Nose wires have their drawbacks too as it makes you more likely to go fiddling with your face near your nose and eyes a lot because of trying to get it comfortable.
