The value of a larger card can depend on what you photograph. I do a lot of soccer and day-long tournaments. The larger cards are valuable to me because they keep my camera in play with fewer interruptions to change cards. The trend of cameras generating ever-larger files implies that one will need larger cards to keep up. YMMV.
Re: brand, I'm partial to Sandisk because they seem to be built better than the others, with the exception of Lexmark (in CF cards at least). The edges of SD cards are somewhat thin and vulnerable and I prefer reinforcing materials thereabouts. That said, I've had Transcend SD and CF cards that serve just fine. Kingston seems a little lesser in quality. If you haven't, I would do some research on SD card performance. Some of the pricier Class 10 Sandisk cards are slower than the cheaper ones.
