Done more outcalls than incalls now by a long chalk and much prefer them to incalls.
Pros:
Out call only girls tend to be part timers - they have not committed to escorting so haven't bothered to arrange an incall location.
Part timers in my experience are more likely to be fresh and enthusiastic, not jaded.
By dint of being part time you will often be their only client on a given day.
Most of my out call regs come to me straight from their day job so no sloppy seconds.
Being their only client of the day often means no time pressure at the end - can lead to longer sessions. 2 hrs can become 3 hrs, or become overnights. An overnight can become a weekend.
It's your place so you will feel more relaxed and at home. You can drive the action - fuck in every room in the house, on every piece of furniture. Always brings back memories after.
No panic for you trying to find the place. No concerns about the neighbourhood. No chance of being late. No chance of running into the last punter leaving or the next one arriving.
If you are pressed for time outcalls are much better as you cut out the travel time.
Cons
I'd find it harder to kick someone out than walk if she's not as advertised.
Nosy neighbours may notice. If you care you shouldn't do outcalls. Personally I don't.
If it's a girl you've not met before you are giving her your home address. Very rarely you can run into a thief / skank as per my avatar who will try and rip you off / threaten to out you or worse. Best practise would be to only see girls who are well reviewed here by punters you trust or someone you've met on an incall first.
Off her own turf an escort may be less relaxed and not give her best performance. That said my experience is the majority don't have a problem.
For me the pros greatly outweigh the cons but everyone is different.
