A minor thing: strokeplus type gestures are partially reversible / cancelable via garbage - I usually do a few random movements if I feel the gesture start is wrong to guarantee that recognition fails. Think there is also a more direct cancellation mechanism, but garbage always worked

However, the bigger flaw vs the pie menu is the lack of those icons showing you the list of the possibilities, so learning is indeed very limited, so you only usually use just a few frequent gestures
