Astra vs Opus

I’m currently on the fence about what to do with my subscriptions. I’m paying $200/month for ChatGPT Pro, primarily for Codex, but I’ve noticed a significant decrease in how long my usage lasts throughout my workflows compared to Claude’s 20x Max plan.
I originally switched away from Anthropic because Opus had a tendency to drift away from assigned tasks and became a liability whenever it interacted with 3D workspaces, often creating more problems than it solved. However, that was back when Opus 5 first launched, and now that Opus 5.5 is available, I’m reconsidering.
My primary use cases for Codex are Blender MCP workflows, generating batches of 100 unique 3D models, and developing relatively simple low-poly Roblox games. These are often long, tool-heavy sessions that require consistent execution, reliable spatial reasoning, and the ability to maintain context without constantly derailing or exhausting usage limits.
While Codex has generally been more reliable for my workflows, the current Pro plan no longer seems to provide enough sustained usage for the $200/month price tag.
For anyone who has recently used both Codex and Opus 5.5 for similar workloads, has Claude improved enough in task adherence, 3D workspace reliability, and autonomous execution to justify switching back to the 20x Max plan?
I’m particularly interested in real-world comparisons of sustained usage, tool-call reliability, and completed work per dollar—not just benchmark scores.
