Reasoning
Mapped all terms to canonical levels (Very Low, Low, High). Treated each URL/domain as a single opinion and weighted it by its reported confidence. Domain-level tallies: SalesRobot leans High, PCMag leans Very Low, Trustpilot leans Low, Nutshell.com/customers leans Low, Salesdorado leans Low, SoftwareAdvice leans Low. The aggregate across domains shows a stronger, broader signal for a relatively easy-to-learn curve (Low) than for Very Low or High. Thus, Low best represents the overall consensus after normalization.
