Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 4.9 for CorePendium against 5.0 for VertiGuide. That said, the two scores are not equally well evidenced: CorePendium has 1.4K ratings behind it against 1, so its average is the more settled of the two.
