Equivilent code, actually.  It's a case of "you say tomaTOE I say tomAHto"
Personally, I tend to prefer the 'block.call' because you explicitly
say you're passing in a block in the definition of the method, so if
someone is reading your code they can easily tell that the method
takes a block.  In the case of yield you might need to read through a
good bit of code before you find out that the method takes a block.
