Verbatim excerpt from one collected ChatGPT answer; formatting flattened, words untouched.

Plivo actually holds a tighter average position (2.4) than Twilio (2.9), yet Twilio leads on first recommendations (4 vs. 3), so both brands are splitting the "winner" signal in ways that matter to different buyers. Bandwidth, AWS, and Microsoft Azure Communication Services are ranked in the category top 15 but went unmentioned here, meaning enterprise-grade providers are effectively invisible when cost-conscious startup framing drives the query.
