Asking which binos are better is like asking which rifle people like better. To each his own. Everyone has different eyes and different hands. Porro prism binos have the zig-zag (the old classic Bushnells come to mind), roof prism binos are straight through sort of like mini telescopes. Many people think that roof prisms are the finest out there but I think this is mainly due to the cost. Roof prisms binos must have more exacting tolerances, therefore the extra cost. But this does not necessarily make them better. If you do some research you will find that one of the finest binos around is, in fact, a porro prism design- the Nikon Superior E. I, for one, prefer porro prisms. They tend to have a wider field of view, and they fit my hands better. I like a wider holding position so that I do not have to force my elbows together when I'm glassing for a long time. The only way to find out which bino is better for you is to go to many stores and try them all. Once you narrow down which style you like then look for features. Pop up eye cups, focusing ring, texture, weight, etc. There are many fine binos out there and you don't have to spend a lot of $. Take a look at Swift, Pentax, and Nikon. The upper level will be Zeiss, Swarovski, Leica. Also take a look at www.betterviewdesired.com. Lots of reviews here and some honest advice. Hope this helps.
