Usually 32KB is best. Sometimes the microcontroller in the card is optimized for burst performance at a certain block size and if you deviate, the performance decreases. I've seen this happen when the card was optimized for 32KB but a reformat changed the block size to 4KB. You could always test the card by copying a large file before and after reformat. If performance is close to what you expect you are fine.
I don't believe the bootloader cares about your block size. I have mine set at 32KB.
