For me it is actually way better than skritter. First of all, it is a single purchase unlike skritter and skritter's android version is really bad.
Also, skritter is way more strict about things. If you do not write a character close to their template it will not be recognized. Pleco works differently, wen selecting fill in the blanks with prompt for characters you will draw them yourself and Pleco will try to recognize your written character and give you a bunch of suggestions, just like the handwriting recognition. You select the character you intended to write yourself, or you do not, in case your answer was wrong.
I tried both, skritter and pleco and for me pleco was the obvious choice.
