I have never had good luck with the tube method (continuous bias binding) of making bias binding. I will cut a square of fabric then fold it into a triangle then cut into strips perpendicular to my fold. I usually save the first triangle cut that would result in a very short length of binding to put into stash for some other use.
I then sew my strips together at a 45 degree angle. The one strip that hits the corner of the square (the coveted "center cut" which will be my longest strip) I will either line up my cut so it hits dead center or recut the ends so they are at the appropriate angle. It is much quicker for me than marking the cut lines, lining them up and sewing into a tube. A 24" square yields a lot of bias binding cut at 2 1/4" width. I can do a queen size quilt with enough binding left over to do a generous size lap/throw quilt.
Regarding the difference between bias and straight of grain here is an excellent blog that explains exactly why a bias binding wears better than straight of grain or cross grain binding (provided you are using a good quality fabric). I don't always use bias binding but when I do, it has been my experience that bias binding gives a nicer finished look and is always cooperative, in addition to wearing better. I usually reserve bias for show quilts, quilts that have curved edges or rounded corners or to take advantage of a print or design on the fabric (like stripes, checks or plaids). Scroll to the center of the page where the blogger does some myth busting when it comes to bias vs. on grain.
