Let me relate a specific situation where it speaks to this somewhat and how it has made a difference in my thinking and decision process for hiring.
About 15 years ago I hired a relatively new and limited reviewed escort who was definitely young and inexperienced. The result was less than satisfying and I just wrote it off as one of those mismatches. Flash forward to last year and I found myself again in the city where this guy was still escorting and since our initial meeting had racked up many many positive reviews. Curiosity got the best of me so I decided, this could be an interesting experience to go back and see if it was any different this time. And was it different? Oh my yes and in a very wonderful way. Had probably the best experience of over 20+ years of hiring.
Was it that he was more experienced or was there something that changed in my expectations or communications of such? I honestly think a combination of both of us gaining more "mileage" under our belts. So while in the past I almost exclusively limited my hiring to guys younger than 25, with some exceptions, that thinking has totally changed based on this experience. I think the experience factor is much more a positive for me these days than just the age. There are many factors that go into the whole process but if it came down to the question as posed by the OP, experience will be the way I would go.
Btw, I have seen this guy three times so far (excluding the very fist time) and plan to continue to see him for as long as he continues escorting and I continue hiring
