I’m probably not the best person to ask since I think most Camps don’t get as technical as I sometimes wish they’d be. These days there are always a session or two on Gutenberg, which is interesting, but I find myself not caring as much about. Otherwise pieces on things like phpunit or unit testing are intriguing, but I’m unlikely to actually use on a regular basis myself. I find that I know too much about the areas of marking and biz dev or social media related talks that have popped up in years past to gain much from them anymore.
For the past several years, the most interesting parts of these camps for me are about the general tenor of the overall web space. I find more value in the “hallway” track chatting with the other folks who are so inclined. Most often, I’ll also check the speakers to catch people who have traveled from distant cities–I find that if they’re developers, they’re usually offering something intriguing. As a result of these strategies I often get more out of camps than just the scheduled talks.
Your mileage may vary.
