GPT

GPT-5 Mini

Prefers Slack0 vs 100

“Slack projects stronger trust and authority: its site shows prominent enterprise logos, customer quotes and videos, usage metrics, industry awards/badges, and clear links to security, pricing, and integrations. Discord’s homepage is polished and brand-forward but lacks the same level of third‑party validation, corporate client social proof, awards, or transparent business/enterprise signals in the provided content.”

GEM

Gemini 2.5 Flash

Prefers Discord78 vs 22

“I would go with Discord (A) because it explicitly advertises itself for 'fun & games' and chilling with friends, which perfectly aligns with a consumer's need for personal communication. Slack (B), on the other hand, is clearly geared towards a professional work environment, with features like AI, task management, and client interaction.”
