Three needle bind off is a sturdy, neat solution to joining two sets of live sts. Knitting even something as small as a bracelet, it's still useful because the seam lies flatter and is less obvious. Rather than pick up sts at the cast on edge, try a provisional cast on so that you have live sts there to join with the ending live sts. Using Kitchener will make an almost invisible join that's worth the extra time needed.
It's not so much that these techniques are faster but that they give a more finished look. Try out them out and you may find you like the results.
