They will be Picco based, and so I think they will be torquey..
To be honest, unless you're racing at a fairly high level where the engine you decide to get makes or breaks you, any engine will do just fine.
From what I know about the Sirio XXX, it lacks on the bottom end and really shines like a light on a straight section of track (I used one and was blown away when it hit the top RPM range) I'm sure they would have solved this issue with newer versions including the Nemesis (not sure on this) but from the engines you stated I would pick:
1. RB T11 (RC has more top end power, not entirely sure on the bottom end)
2. Novarossi Flash .12
3. Max XXL3
But the Picco Torque engines definitely have plenty of power on the bottom end, the Evo 3 when I had one was an absolute ripper.
