The Bushnell 7x26 is the best affordable small binocular in existence. The Yosemite is one of the true bargains in the optics market. The optics are really pretty comparable, but the Yosemite is a lot larger than the Bushnell. So the ultimate choice will be the size of the binocular. The Yosemite is small enough to be easily packable and large enough to be comfortable to use all day. The 7x26 has superb optics, but it is small enough to be difficult to hold and do much long term glassing with. The 7x26 is a little too large to be pocket size.
I have both and they are really an apples to oranges comparison. I guess if I had to choose just one it would be the 7x26.
