It really boils down to gameplay style.

If you like hanging back, kiting your opponents, and scoring hard hits, I recommend the Norcar.
 
The Sodak is more for fast-paced hit-n-runs where you run in for a quick hit while the enemy is distracted and get out of range before he can hit you.

I've played both, but I prefer the Sodak at higher levels because it's a lot faster. I run it with 2 front guns and I rush deep into enemy range. I find it easier to get kills up close where you know the proper gun angle and your enemy is struggling to find his (since you're going 49ish knots).

At-level, both ships will be worse than expected, but when you get good with them, both can be just as dangerous and fun 

Some differences to note between sodak and norcar:

Sodak: Greater speed, moderate power, 40 degree max shot (lower=better for rushing), bad spread at-level
Norcar: slower, but hits rather hard, 45 degree max shot (higher=better for kiting), slightly worse spread at-level

Yes, sodak is faster and can dodge better while nocar has more range and firepower.

Both are good. You will need good crew to get the best from these ships tho.

Personally I had more fun with sodak but I did great games with nocar too.

Thanks for replying guys. You helped a lot.
