Honestly the idea of best in terms of paintball guns is merely a marketing ploy... show me a brand new paintball marker that is substantially better than an 04 viking, 06 cyborg, etc. Nothing shoots practically faster, nothing is practically more efficient.
People say oh it has more kick, oh it's smoother, it's 5 oz. lighter... laughable in actual function unless you have arms like pipe-cleaners it makes no difference. And if 5 oz. or even a pound makes a difference to you then I would suggest you spend your money on a gym membership and a strength coach because you've got problems.
