In your opinion, whats the best brand of cocoa er?

In your opinion and from your experience what is the best brand and product of cocoa er? Is there a difference between cocoa er and cocoa er cream or is it the same thing?Im 5 months pregnant and since the beginning I've been using the "Palmer's Cocoa er Formula Tummy er for Stretch Marks" it comes in the little circle container (so far its workin pretty good I just want to know what other people use and how well it works)..I was just wondering if anybody has any other suggestions for any other kind of cocoa butter or stretch mark formula..
