For example, Steve Howell, who many would agree is the best pelagic birder on the planet, uses 8x and I promise you he spots and identifies more seabirds with those than anybody else, regardless of magnification.
A lot of it is personal preference. I prefer 10x for everything, but I also have very steady hands and have no issues locating birds with them in the woods. People who do mostly forest birding tend to prefer 7x or 8x because you get a wider field of view and, on average, a little bit more light. I think I've met maybe one person who regularly used more than 10x bins; I think those are more of a novelty and the handshake really is a problem at that length.
