Shall I keep the blonde or go back natural?

For the past year and a half, I have been bleaching my hair regularly every 4/5 months. I am due to get it done again as it has grown out but I’m unsure if I should go back to my natural colour instead.

I (24 F) have been yo-yoing between some form of blonde and my natural colour since I was 13. I always seem to get the blonde itch once I finally get my hair healthy again.

The money and maintenance isn’t really an issue, however, I’ve always not had the best experience when getting Ballyage/highlights,etc and have always ended up with stripey, orange, or uneven hair resulting in having to go back two or three times to get it fixed. I’ve also been to about three different hairdressers at this point. I don’t know if I’m just picky, but whenever I post on Reddit people seem to agree with me. Maybe I just have bad luck with hairdressers.

Anyway, I have tried to include lots of photos with my hair naturally dried versus styled and with with different haircuts so you can get an overall picture. FYI in some of the photos I have my eyebrows natural, and in others lightened as I felt that looked softer with the blonde. I feel like with both blonde and brown my hair sometimes looks good and sometimes not so good. For reference, I also have finer hair so either way it usually looks a little bit flat.

Do you think I suit the blonde or dark better?
