Because of this, all new high-end guns have a similar level of performance: all can fire as fast as you can pull the trigger, all have regulators that allow for consistent firing and barrel kits are available for all so you can match your paint perfectly to your barrel. When you choose your high-end gun, no gun truly outperforms another - it all comes down to the feel and the look of the gun and what works for you.
Despite all this parity, you should keep a few things in mind: not all guns are as reliable as others, and not all guns cost the same. Before you buy, be sure to read some user reviews on reliability and remember that new models tend to have problems that are usually not worked out until the second shipment of guns a few months after release. In terms of price, more isn't always better - the "hot" gun for the season might cost $300 more than last year's model and the only difference is some cosmetic milling and a new on/off.
When you choose a gun, try to focus on how that gun works for you. Do you want something large that fits comfortably in your hands? Something small and light that lets you snap shoot around bunkers? A feather-touch trigger pull? A trigger with some play? A circuit board that has a breakout mode or ramping mode? A body designed for cosmetic upgrades? Choosing your high-end gun will be similar to choosing a high-end car - are you a Corvette person or a Porsche person? Performance is similar put the different packaging fits different people. You'll always be able to find someone who loves a certain gun and someone who hates it so be sure to simply choose what you like best because after all is said and done, the gun doesn't make the player - you can have the best gun in the world but that won't substitute actually playing the game.
