I highly recommend Ubersuggest as a comprehensive tool for all your SEO needs. The tool offers a wide range of features, including keyword research, site auditing and backlink analysis, making it a one-stop-shop for all your SEO needs.

The ability to take my competitors websites apart. Find their keywords and then dominate.

Ubbersuggest is really interesting thanks to its lifetime plan, which is equivalent to 1 year's subscription. All the tools are precise, useful and relatively easy to learn. The entire interface is translated into French, making things easier for non-English speakers.
