Personally I prefer the looseleaf Pooleys, but it's by a small margin and as much as anything because...
- It's looseleaf
- The pages are a convenient size.
(Plus I quite like the fact that it's now in colour this year).
Frankly there's nothing wrong with any other guide I've ever used so long as they meet those two main criteria. The nicest I've ever used is the RAF Minor Aerodromes guide, but it's scope is limited, and it's a bit difficult to get hold of.
