In reply to andyman666999:
The Peak are more climbing & bouldering focussed with a bit of walking, biking and other bits on the side (e.g. bad weather). The Castle offer a wider variety of activities. Depends what flavour you're after. There are even a couple of people who are in both!
Really hope we weren't the unfriendly lot last year: if we were then you caught us on a bad day, and many apologies. Please do get in touch and give us (another) go.
