In my experience taking literally thousands of photos with my Olympus E-500, the main advantage is the faster cycling speed (the speed the more pics you can take.) Not so much have I found there to be an advantage to download speeds. I patch for that see the end of my post.
These cards are proprietary to Olympus & Fuji only (see more below), and if having a choice in the issue, and for the little more I would go w/ the H since it does take a faster photo, meaning times you can click between them. In addition, the storing of the photo is faster on the camera, and this is what enables one to cycle shots faster......

"Olympus and Fuji have worked together to produce the xD card. These cards are smaller than SD cards (25mm x 20mm). All current Olympus and Fuji consumer level digital cameras use the xD card to store photos on. There are three types of xD card. These are the H card, M card and a standard card that comes without a letter. The standard card was the original xD card. The two newer types were introduced because they could hold larger numbers of photos. The H card is a higher speed card. This means photos can be stored more quickly on the card. This can increase the speed at which the camera is ready to take the next shot. The M card and the standard card are both normal speed cards."
I shoot all of my photos at SHQ: 3264 x 2448 1/2.7 Approx. 6.4 MB each. You are talking 1 1/2 hours to download 600+ photos on a laptop. For faster downloading to my computer, desk top at home and laptop while traveling, for $25, a fabulous investment was a Lexar USB 2.0 Multi-Card Reader
I am no expert, but this has been my experience. Hopefully others can join in with their knowledge.
