First of all I work for
http://www.worldcollc.com so I may be biased, but it is not even a contest. I can see a very experienced day trader wanting to work at the comfort of home but for new traders you gotta go LLC (unless you are the lucky few who can work for a big firm's trading desk, without an Ivy League degree you gotta start with a LLC)
I have been trading for 8 months (turned profitable 3 and 1/2 month), and I am given 1500 share positions and 12 positions, plus a 92% payout (and IB commission rates). Keep in mind I do not have a degree, only 21 year old and there is no way in the world I can get that kind of capital on my own. The fastest way to build capital is if you have access to a large amount of capital, and most new day traders fail because after they lose 10-20K or so their trading size is severely limited, frustration compounds, pressure builds up, and you are out of the game. My firm takes huge pressure off your back because when you are losing your shirt you are NOT losing your own money, and you still have the resource to trade big sizes to make it back . . .
I was getting nowhere when I first started, then I met two (relatively new but more experienced than me) traders who were willing to share, quickly I made adjustments and started to make money. There is no better feeling in any job when you have a trusty teammate who can come up with big plays when you are on a cold shooting day . . . A firm provides you a pool of talents to work with, and a lot of potential mentors . . .
Throw in technical support which takes a lot of burden off your back, and bullets/conversions that gives you a HUGE edge, it is not even a contest, trust me . . .
P.S. I also like Schoenfield, but their payout is too low . . .
