I like it better than the older 10-hex hexes I designed because it has complete hexes in the corners, and the numbering makes it easier to key.
As with any hex grid of this sort, you can zoom in on individual hexes just by drawing on another sheet to a larger scale. If your top-level map is 10,000 kilometres from side to side (1,000 kilometres per hex), the next level down would have 100 kilometre hexes, then 10, then 1, then 100 metres per hex, and so on if you want to get really detailed.
Below are links to a couple more, one of 4 hexes side to side, the other of 7. Trying to keep complete hexes in all the corners means you can't really manage an elegant sequence of sizes; four is useable maybe, but I'm not so sure about seven.
