You can access a table done with Google Docs where we compare this URL shortener to others. Many features are compared and a score for each URL shortener is calculated. A lower score is better.
As you can see, tny.im has the lowest (best) score, but make sure to look at other shorteners too!
Should you think our comparison has problems, we encourage you to do one yourself using your methods. If you do it, we really appreciate that you share the conclusions with us - we may even end up pointing to your comparison!
