Google's NLP is among the most accurate — especially strong across 30+ languages natively
CX visual flow builder handles complex multi-turn conversations without becoming unmanageable
Deep Google Cloud integration with BigQuery, Cloud Functions, and Contact Center AI
Free ES tier is genuinely unlimited for text requests during development and testing
Version control and multi-environment support make enterprise deployments manageable
Voice agent support with natural speech recognition and synthesis built in

Per-request pricing on CX gets expensive fast at high volumes — $7,000 for 1M requests
Documentation is scattered and mixes outdated ES content with current CX guides
Migrating from Dialogflow ES to CX requires a complete rebuild, not a simple upgrade
Steep learning curve — requires GCP knowledge and development experience
No real no-code option for non-technical users who want a simple chatbot

Deep integration with Microsoft 365 apps makes AI feel native, not bolted on
Excel formula generation from plain English is a genuine game-changer for spreadsheet users
Teams meeting summaries save hours of catching up on missed calls
Free tier includes GPT-4 and DALL-E 3 image generation with no account required
Enterprise-grade security and compliance inherited from existing Microsoft 365 infrastructure

Microsoft 365 Copilot at $30/user/month is very expensive on top of existing subscriptions
Quality varies wildly across apps - Excel is great, Outlook drafts are mediocre
Standalone chat experience is unremarkable compared to ChatGPT or Claude
Cross-app intelligence promised in marketing demos often falls short in practice
Requires Microsoft 365 subscription to unlock the most valuable features
