# SOMA Compression Algorithms - Comparison Matrix

## Quick Selection Guide

**Need 99% compression?** → Performance-Focused  
**Need 95% + preserve errors?** → Aggressive Hybrid  
**Need 83% + code-friendly?** → Code-Focused  
**Need 4% + balanced?** → Hybrid  
**Need 0% (preserve all)?** → Dialogue-Focused
