SheerSEO

I have bought access to lots of SEO platforms, but SheerSEO has several features that make it stand out:
1. Simplicity. If you are familiar with SEO, you won't need any tutorials to start using the tool.
2. Majestic SEO link database. This was the key selling point for me. Why pay monthly for Majestic, when you can get access to their links by purchasing this lifetime deal?
3. Last but not least, Ayal has got your back with top-notch support. I didn't have such a good experience with other sellers, so this factor has become really important for me lately.
