A little late to the conversation, but (St) Corneliu hasn't been officially Canonized (although he is locally Venerated, which is the first step towards Canonization).
Unfortunately, the Romanian Orthodox hierarchy are some of the most liberalized in the East, so I doubt he will be Canonized for a LONG time. The Romanian hierarchs are terrified of anything Legionary, or anything anti-Ecumenist, this is why they are still reluctant to Canonized Elder Justin Parvu or Fr George Calciu, as they were both Legionaries and very anti-ecumenistic. Fr George was just recently reburied, and his body was found to be incorrupt; this, along with the other Miracles attributed to him, show that he is indeed a Saint...even if they never officially Canonize him).
As far as the differences between Sima and Codreanu (Corneliu's Father) go, my biggest issue with Sima was that he was moving the Legionary Movement away from being Christ-Centric, whereas Corneliu's dad wanted to maintain the course his son set.
