Martin, 25p is a frame rate and 1080 is a resolution. The faster the frame rate the smoother the motion will be. The higher the resolution the clearer the image will be, even after a down convert.

IMHO, choosing a bitrate is determined by size requirements, delivery mode, quality of the actual video, motion in the video, and intended output quality.
In some cases, a single pass encode may not be enough to get a good quality output with a low bitrate.
Edius doesn't have a dual pass option, but TMPGE has the AVC plug-in that does have a dual pass option.
When you get into the lower bitrates you will need to test what works for you.
It's not always a 'one size fits all' scenario.
The biggest space saver would be a dual pass variable encode. If size isn't an issue I always use constant.

I'm doing more H.265 outputs through NVENC and Mastering Works 7.
I don't have the H.265 QS option on my system.
NVENC allows me to speed up either H.265 or H.264 files by leveraging the horsepower of my GPU(1080ti). I use constant on these exports.

You just have to experiment to determine what works best for you.
