Pelham versus slow twist snaffle?

I know that question wasn't directed towards me, but I suggest this one.

Last weekend I drove a couple hours out to the nearest tack store, and I wasn't even needing a new bit, but this one caught my eye. I loved the look and feel if it SO much. I seriously almost bought it, just to have it around.

I don't ride in a Pelham , and don't have any personal opinion pro or can about them, but this discussion reminded me of a book I checked out from the library and read some years ago by Heather Moffet, who is very pro Pelham bits.
Actually, the whole book was really interesting and had some neat info in it
