A and C, I think you will find I am being objective, my first post said
"There are benefits to both ways, it's down to personal choice really"
You can't really get more objective than that!
My point is when people do these comparisons they don't do them fairly, people will quote a UK figure for eg £70 an hour and then say things like " well in the US, you have to pay for food, housing, flights, out of pocket expenses, going out, transport, etc"
In the UK these expenses will also be incurred but dont seem to get counted, on top of the landing fees etc.
I'm not trying to push a personal point of view, merely pointing out you need to work out the true cost of both methods and compare like for like.
