War of the roller lifters...

So as flat tappet cams usually receive a negative connotation these days, most are making the switch to roller setups. My question is what does everyone have for input on brands they like for hydraulic or solid roller lifters? Beings that I use to be a flat tappet guy and am only JUST getting into roller setups the factory hydraulics seem to actually be pretty durable for getting beat on but maybe everyone has other preferences?
