CMC Markets vs. Bell Direct - New online trading a/c

Anyone have any experiences using the margin loan facilities of these brokers? They more or less pay the same interest, however CMC uses an actual bank account to settle and hold funds (vs Bell's cash trust) and using a linked Suncorp loan you pay the same variable interest as Bell. Brokerage is $11 at CMC vs Bells $15.

Suncorp's buffer is 5% vs Bell's 10% value of the geared shares, but Suncorp has more on their approved list and looks to have a slightly higher average share LVR too. I'm kinda torn, however Bell has far less paperwork.
