Plssss... Anyone??? HELP!

Dear all...
I am a fresh graduate and have just gotten 2 offers at 2 different Recruitment Firms.
"A" is a medium-sized firm with branches in Singapore, Malaysia, Taiwan, Australia, including partner companies in Hong Kong and Japan.
"B" is a small-sized firm with branches in Singapore and Malaysia only.
"A" offers a lower Basic Pay, but higher Commission, however if I do not reach my quota, they would cut 20% of my Basic.
"B" offers a $200 higher pay, but lower Commission, and do not cut my Basic even if I don't reach my quota.
Both companies, A and B has been established for 10 years. Company "A" has grown into different branches around Asia, and COmpany "B" has not achieve that much.
Question: Which firm do you think I should rest my career on??? Which offer should I take up? Taking all the aspects of both companies into consideration. Plssss plsss plssss advice................ I'm so confused...
TQ soooooooooo very much!

HI,
Look if u really think u r competent enough to fulfill the targets of co.A then head towards it cause if u give ur best there ,chances of your bright future are more.
I think u must think positive and head towards a challenging task rather than a comforting one for ur start.This will boost your confidence in yourself and you have something to add in your positive triats but GIVE UR BEST.
ALL THE BEST.
