I think it really depends on which pump you're using and which brand suits your BB most.
I use the Avent pump, so to avoid too much hassle, my BB uses Avent bottles.
However, there was a time when he's tried a lot of different brands of bottles as he hates bottle feeding. He's tried: Nuk, Mothercare, Playtex, Medela Habermann, Bebe comfort...in the end, the best out of the lot was Avent (although that means the most he can take is still only 2 oz each time :-( )
