What's the best order for bosses?

Seriously, though in every list Goumang will be considered first as I defeated her first. I haven't completed any other Sols yet tho so please comment your opinion!

1,2,3 can be fought out of order. This is helpful since the beginning is the hardest part. 4 and 5 are linear. There's also a choice between 6 and 7. 6 is much, much harder than 7.
