Intrepid vs FTLO vs Flashpack for 30s tours

I’m interested in the idea of a group tour that might have people around my age (I’m 34)

I’d be interested in a somewhat social group of people my age, but also not exactly interested in just hours of drinking every night. I don’t drink, happy to tag along to bars, but I did a intro travel tour before and I felt like we were missing potential sightseeing at the expense of people drinking

Also preferably I’d like a guide who actually has knowledge about the trip, vs just someone whose role is herding people together

Also happy to pay extra for actually premium experiences, but don’t need to pay extra for bad experiences

Intrepid has been good before, but also has more older people and groups so perhaps less social environment

Interested in people’s experiences with FTLO and Flash Pack, seen some pretty mixed reviews in threads, but was hoping to hear from people who have experience with groups like this

Thank you!
