If you put in a pinwheel, that would be a straight seam wouldn't it? So stop stressing and do what you have to do to finish the quilt. I have used both and they were fine. I have even used straight seams to join pieced binding if it looks better.

Straight seams tend to break the eye if breaking the eye is important. Sometime it matters and sometime it doesn't.
If entering the quilt in a show it may be an important consideration.

I just did straight seams because it was a varigated fabric and it had to flow continuously. BTW - the directions said to! ha ha

To me, it matters whether the blocks are set straight or on point. With a lot of straight 90 degree seems, the angled border seam would be more eye-catching.

I've always used straight seams on borders, unless I could avoid a seam altogether (which is my preference, but sometimes that just doesn't work out!).

So far nobody has died from it, and none of my quilts have burst into flame. ;-)

I think it probably only matters if the quilt is to be judged. I doubt a non-quilter would ever notice the seam either way.

This is something I had never heard before. I have always used straight seams and they work just fine.

Seems I remember reading somewhere (probably here or Quiltville) . Borders 3 inches or less look better joined on an angle, wider borders joined with a straight seam. So that as always been my general rule of thumb unless my amount fabric tells me otherwise.

I've found that most of the "rules" of quilting are really just suggestions. You're creating it, you're the designer......it's your call. I'd say if you can make it fit with straight seams, go for it.

I use straight seam a lot and they seem to work out well. Try sewing 2 pieces of scrap fabric together, press and see how the seam looks. If it looks OK to you go for it.

Straight is fine and I find it more dependable to keep the border laying flat. The eye will follow the quilting pattern, not the seams.
