MLX relevance questioned for Mac users as llama.cpp matches performance

A user on Reddit is questioning the continued relevance of MLX for Mac users, specifically in September 2026.

This development leads the user to wonder if there are still compelling reasons to use MLX, especially for specific models like Qwen3.8 27b on an M5 Pro, and asks if their observations are accurate or if there's a specific configuration they are missing.
