I've sailed most of the boats you've mentioned, and I like the Tiger, but if you're a novice to cats, you may find it overwhelming because the ride downwind (actually on a broad reach) is flying on an edge.
I'd stay away from the Miracles because they're strictly a racing boat and not beach-friendly.
I really don't see how an H20 is less friendly then a Tiger on the beach.
If you know how to sail I would recommend buying the most popular racing boat in your area.
On the other hand, if you are still learning I would recommend a tougher used boat that you can make mistakes with such as an H16, TheMightyHobie18, P16, P18. You can typically pick these up cheap and then move up in a year or two without loosing too much value. If you are a beginner and want a new boat I would recommend the Getaway.
The Tiger and H20 are great racing cats but they are overwhelming for beginners. You can turn one over in the surf and destroy a mast the first time out and really sour your day. It would be a very rare beginner that can start on these boats and not be in over their head.
