The case of the 5565 never appealed to me. It's a weird hybrid between a crisp edged case (overall shape) and a soft curvaceous case, leaving a broad ill defined bezel, lugs, etc. that's neither fish nor fowl. The 5100 on the other hand is well defined and assertive but not severe. Toss in the special movement of the 5100 compared to the pedestrian cal. 215 in the 5565 and it's no contest.
