Your Opinion Please

Which is more logical - Mini Sites of 2 or 3 pages that sell, or Theme Based Content Sites of 50-200 pages, that provide information and Pre-Sell people and refer them to merchants ? There seems to be a great deal of disagreement on the Net about these two subjects and which is best for profits in the short and long term.

I tend to favor the second option because I think people are looking for information on the Net, and if they find a Sales Pitch instead, would it not drive them away ?

Any thoughts on this ? Has anyone ever tried both concepts ?

Thank you in advance.
