It comes down to fit, not a single winner: Scalenut leans into keyword and topic cluster planning, while Shortwave is built for voice-aware AI reply drafting.

Shortwave is the lower-cost place to start thanks to its free or freemium plan; the other is worth a trial if its feature set fits better.
Shortwave has the higher AInexfinder Editor Score (our editorial rating from features, value and pricing, blended with verified user reviews where a tool has them), but "better" depends on your needs — compare features, pricing and the pros & cons above to decide.
