Best competitor analysis tool?

I saw that ahrefs improved their competitor analysis, which is good. But it costs $200 each month. Semrush is cheaper, but not as good. I also checked out mongools, it’s okay. I want to find topics and keywords with lots of searches, and topic gap seems important. Is ahrefs the best for this, even though it’s pricey? Is there something similar but cheaper, or a way to pay less for ahrefs?

Ahrefs excels in topic and keyword research, but consider Ubersuggest for a budget-friendly alternative.

Look into shared access or free trials to reduce costs on platforms like Ahrefs.
