it's all subjective and a matter of personal taste but i think you have a little bit of a "Goldilocks situation" w those three choices....too big....too small.....
two of those are big bodied dreadnaught body size/shape gtrs. those are generally favored by bluegrass players and solo singer/songwriters as they put out a lot of volume and lots of low end bass booty.
you certainly CAN play blues on them (or ANY gtr) but i'd have to say that's not the most popular size/body style for blues guys.....more often they prefer smaller bodied gtrs that do a better job w mid range and high frequencies.
both of them have full length/full scale necks...the YAMAHA however has a very short scale neck that might actually sound pretty good for blues providing you don't have bigger hands. the down side is that chords might be a little "cramped" because the frets are much closer together.
if you're interested in playing blues you might also look at some resonator gtrs in that price range. i've been impressed w some made by ROGUE. good bang for the buck.
bon chance!
