Im a fan of the DM6, which happens to be only Dye marker I own. I feel its right when matrix features peaked. I also hate idea of having a insertable plastic piece that my paint sits in the breech. Its not without its downsides as some people mentioned. My biggest gripes with it are ergonomics, it does not balance well at all. The way the reg sits at front feels awful to hold, I helped fix this by adding MacDev tank spacer to make reg longer which lets me actually wrap my hand around it.
Currently for the price I think its an amazing value. None of modern matrix seem to shoot as smooth as older GenE, and I honestly have no clue why other than weight.
