I guess it is just a matter of taste. Same with just about everything else (food, tools, mowers, cars, trucks, etc. etc.). We have an Edgit attachment on one of our Shindaiwas and like it very much. Of course when I say "We", I'm only talking about my son and I. As far as how many people out of one hundred would like the Edgit?, I couldn't say. But I'm fixing to order another one because my son and I are always fighting over who gets the trimmer with the Edgit attachment. It felt a little odd using it the first few times, but now a regular trimmer feels odd to use (go figure). If I were you I would order one and try it out. If you do, use it a few times before you make a judgement call on it. I wouldn't be without mine.
