I personally noticed a BIG difference in the driveability of my car after flashing to stage 1 (I drove it stock for 6 months before flashing it). Not just HP and torque but it spread the torque over a much wider (flatter) power band, which made the car much more driveable than stock.

So I would suggest driving the car for a while with the Cobb stage II map and see how you like it. If I understand correctly from my research, a protune will gain you more HP/torque. The Cobb maps leave a lot of HP/torque on the table in the interest of reliability. So it's up to you whether you want to press the edge of the envelope or be satisfied with a reliable OTS (Off The Shelf) tune...
conservative does not mean safe!!! My Cobb VF39 map was consistently pulling timing..meaning...yes..knock on a shelf map. Not only is a protune safer and more reliable but you will make more power with better response and the onset will be smoother and more refined.
