Should i buy an eyeshadow palette or just stick to the individual ones?

It's a much better deal to get the 88 color palette. There is a section on that link you posted that had reviews on it. I read some of them and they were all excellent. So, if you're concerned about the quality it seems that other people have used it and they really like it. If I we're you, I would definitely get the 88 color palette. Especially since you said that you like to experiment with different colors.
