Need some opinion on education fund. 2 questions:

1) Anybody knows which insurance company provide a better education fund? Planning to get an education fund/insurance for my 2nd newborn. I already have ING education fund for my 1st born

2) I'm beginning to think whether it is really worth it to buy education fund as I can invest in other instruments to get better returns (although with higher risk). I guess education funds has its advantages and disadvantages but I want some views on it. Any opinion is much appreciated

Note : I do diversify my investment and education fund is just another investment with different advantages/disadvantages and risk/returns.
