I have used all three a good bit. All have their pluses and minuses. Ripcharts is least expensive and more coverage. Hiltons has more rigs listed and is a bit more expensive. (Have to buy two zones for full gulf), Roffs is expensive. It's pretty damn good though. Especially on current and lines. All are good. Just depends on the pocketbook.
