What matters is not what you log, but what you need logbook entries for in the future!!
Let's say you want to do the FAA CPL one day. Then, you will need a 100nm VFR cross-country flight with an instructor, and I believe another one at night. Not easy to do the latter in the UK, since night=IFR
That is the sort of thing one wants to meticulously log, and get the instructor's signature next to each such flight just to make sure nobody can argue with it.
I've just discovered that I have 8 hours last year, FAA rules, IFR across Europe, dual, which was logged PU/T when it should have been logged P1. But who cares?
