Really depends. In my case I needed 30" wide x 10' long for my project so two sheets covers me where it would have taken 3 sheets of 4x8. Since at that point the cost was about the same I went with the higher quality BB which is so nice to work with ?
Having said that if I was building cabinets i would have gone a different route. What I typically will not do is buy big box store plywood, while cheaper I have just had to many issues with it. I bought a sheet from Menards a couple years back and it was so bad as I cut it up it started delaminating, while I suspect this was a manufacturing defect, and they did actually refund my money on the cut up sheet, I now try to only use higher quality plywood. It cost more but so much nicer to work with.
