Default OS 21 spec or Novarossi 21

Ordering a new motor for my Losi 8ight 2.0
I am looking at buying either the OS .21 VZ b vspec or the Novarossi Plus 21-4 Factory Tuned 2009 version. Which is the better way to go? What is better on gas? What one has better power? Please tell me the pro and cons.
Been out of the RC world for a few years so any positive input much appreciated. Thank you in advance.

And the longevity. The Nova will probably last twice as long as the vspec before needing any type of replacements/pinch.

The +4 will be much smoother running of an engine. Good for buggy.

If you are going to buy a vspec go with the ninja (made by o.s.) coated and silicone filled crank, better case and super easy to tune. 30 bucks more then a vspec and last twice as long as a vspec that will rev to the moon and back. Comes with a 7mm restrictor and get excellent run times.

really thease are two of the top engines. Preference.

I love my OS, but I would probably choose the +4 with out thought, Vpecs are done, no more, discontinued.
