OK. There are differences between recorder models.
Especially when it comes to editing and extra features.

I have Philips +RW recorders (of the older model types) which can
record on +RW or +R. (No HDD in those.)

I don't use DVD+R in the recorder. I burn permanent discs (mostly +R)
on the PC after adding menus, correcting 16:9 flag etc.
Or I just copy a +RW I edited on the recorder on to a +R if I want a
disc to keep.

On a PC there is no practical difference between +R and -R (besides
the inherent buffer underrun capability of +R and compatibility
differences one can have between recorders and players).

The Philips standalone can record on +R right away without formatting.
But post edits on disc (hide and new chapter marks) is only visible on
a recorder, it can not be visible on a standard DVD-player. Only
chapter points created while recording fare visible to a DVD-player.

So I use +RW in the Philips recorder with the main features:
+ Records right away (without no extra formatting command).
+ Plays (and extracts) right away on a PC or standard DVD-Player.
+ Philips recorders replicates the 16:9 aspect flag in SCART connector
as it was changing during the recording, when played back on the
recorder.
+ Post edits (split/hide and new chapter marks) can be made compatible
with DVD-players.

There is one negative point.
- Time jumps are disabled when played on a DVD-player.
