I always really liked the Pal Park game, and I'd usually try to transfer "rare" Pokemon in order to get a higher score. I thought having to run around different areas was pretty cool, and in the end you would end up with your Pokemon and a berry.
I'm not a huge fan of the PokeTransfer system though. The two DS thing was a pain in itself (although there aren't many other options, given the fact that there's only 1 cartridge slot). The mini-game got annoying after the first few tries and I'd definitely prefer if they went back to a PalPark scenario, since that was so much better, in my opinion.
