We all have our individual preferences.
I like the feel of speed in a photo and I get a lot of one star shots to prove it.
One thing I do is to shoot at a higher shutter speed first- that ensures me of a good crisp shot. From there, I lower the shutter speed for the best motion blur. If I get enough opportunities to shoot the same subject, I'll go into the insanely slow speeds- 1/20th - 1/60 zone. These really slow ones are usually trash but occasionally I'll get something really interesting.
***There are times when I do freeze the action on motorcycles though.
