There are a few variables involved when finding a DE blade that is best suited to you personally. The same DE blade may behave differently in different razors and how sensitive or not your skin is. If you have more than 1 DE you may have to try different blades in each to see what works best for your skin sensitivity.

A sample pack of different blades is a good place to start in order to find the best blade before making a bulk purchase.

As with using a straight razor do not discount how important having a good lather, proper angle and a light touch is either. I could not use an aggressive DE with a Feather blade before I learned how to shave well with a straight razor. Now I enjoy using an aggressive DE and Feather blades simply because I learned to make a very good lather, find the right angle and use a very light touch.
