My straights don't get as sharp as the Feather blades in my Feather SS, but the shaving difference is not really noticeable.
I would suggest that you are on the steep end of the learning curve, and it took me a month or so before I could feel any comfort with the shaving itself or the results. It does take time, and you have to put that time in. I can tell you that it is definitely worth it. Once you get past the usual Newbie issues, you'll be on your way. Be patient and persistent.
