I'd put my money on SD and SDHC cards. They're more compact, come in a larger variety of sizes and speeds, and are also (even though you don't care) generally cheaper.
And just as a little side-note, certain camera manufacturers use certain card types in their cameras. Compact Flash cards are often used in Canon models, just as Nikon employs SD cards in all of their cameras. Pentax cameras utilize either/or, as do Olympus cameras. Sony cameras are the sole users of Memorystick, or MS cards.
