Hey, wow...I didn't think planetside-universe even put up my guide until I read this thread, and it has over 3k views! :O I feel special! Heh, wrote it like weeks before public beta even came out so there is a ton more I could add. But to address your question, most of my kills are from boomers actually. Today I got about 20 kills alone from boomers and about 10 from the AMP. The reason I chose AMP over the scatter pistol is because it has a high refire rate and does a lot of damage. Example, today two hackers were at a CC in a tower and I crept up right behind them. If I would of had the scatter pistol (6 shots) I would not of been able to kill both but the AMP has enough rounds/speed/damage that I was able to kill both in a matter of seconds. But it's personal preference, try both and see what you like the best.
