Pace your biggest problem is that you put ATC into the equation
Widebody sorry using the word ATC too loosely
infact where there is proper ATC like EGBJ ATC tend to be more accomodating fitting faster aircraft where they sense the experience of the pilot onto more direct joins while the rest are flying SOHJs.
It is often the clubby fields with just radio who are the worst and demand OHJs regardless of traffic or otherwise.
My preferance would be the 45 degree join as that covers lower cloudbase and weather without throwing confusion into the equation or as I said before even more confusion in marginal OHJ conditions
But all to their own
