Studio Perfect vs. Lightful foundation?

[BlahWah]

What's the difference between these two, besides the spf, e.g. with coverage, for dry/oily skin, etc.? Also, what is it like to the Pro-Preferred White Matte foundation? And lastly, how much is it (in currency of location it's found in)?

Sorry for all the q's, but I'm hoping to find a better foundation, one that's more yellow than orange on me, and I'm hoping these would be it.

Thanks so much!

Anyone? Please help! This would be a huuuge investment for me (just convincing myself to get one of th foundations over here was an ordeal) and I don't want it to bomb. Members in Asia, please give me your 2 cents! They're very much valued!
