Yeah the Wattz 2000 will be more powerful than the AER14. After the patch the AER14 does 35 damage (compared to 22 before the patch, lol), while our Wattz 2000 will do somewhere between 40 and 45 damage, same league as the hunting rifle and sniper rifle.
The main advantage of the AER14 over the Wattz 2000 is that the AER14 can be fired rapidly, same speed as a normal laser rifle, while the Wattz 2000 has a firing speed like a hunting rifle.
The energy weapon boost by Patch 1.2 wasn't perfect. A simple example is the base Laser Pistol: same pitiful damage! Now with the Plasma Pistol boosted to nearly x3 DMG for x2 ammo consumption, I really don't see a practical use for the Laser Pistol. By contrast, the Laser Rifle is now truly viable as a mainstray weapon.
The most comomn type of laser pistol, simply called "laser pistol", is now the classic Wattz 1000, whose item description said it was a civillian laser pistol weaker than military models. So it makes sense for it to have that low damage, but we are still probably going to boost it from 12 to 14 damage. While the model of laser pistol seen in Fallout 3 and New Vegas (the AEP7) is now the "Combat Laser Pistol" and will be doing damage around 18 so it does as much damage as the post-patch Recharger Pistol. (The Combat Laser Pistol will be rare but you can find it for free, but you can only buy Recharger Pistol from the Silver Rush.)
