I've used Alien Bees. The main issue is, I'm going to be doing a lot of photos outdoors, with a variable ND filter, and the goal is to dim the sky/background as much as possible when I feel it would fit. I feel I'll need 1200w/s of power at about 5 feet from the subject to do this at my 1/250 sync. That would put me at 2 AB1600s and a Vagabond Mini (which is awesome, but a couple month wait). That would put me at roughly $1000. One Jinbei 1200 w/s w/pack is rougly $550.
However, ABs are great and have a name for themselves. I've talked to
this guy on another board, and he loves his Jinbei. This is coming from a former user of Elinchrom Quadras and Ranger ASs.
This is more of a share thread, than opinion. We seem to have a lot of lens bragging, body bragging, but no one really posts their lighting.
