Semrush alternatives that don't break the bank - honest comparisons

Semrush is powerful but the pricing jump from Guru to Business is brutal for small teams. Need alternatives that cover the core jobs without the bloat.

Looking for head-to-head comparisons on:
* **Keyword database** - Size vs. relevance for local/niche markets.
* **Rank tracking** - Update frequency and accuracy. Daily vs. weekly checks matter.
* **Site audit** - Crawl depth and actionable fixes, not just a score.
* **Actual cost** - Per-seat vs. feature-gated plans. What do you really lose on the cheap plan?

Specifically eyeing Ahrefs, Moz Pro, SE Ranking, and Ubersuggest. Anyone run these side-by-side on real projects? Not interested in affiliate pitches, just what you actually use in your pipeline.
