Hi there, I’m trying to decide between Antigravity Ultra and Claude 20x , since both are in a similar price range for me. I’m specifically interested in the current state (2026) — especially after the release of Opus 4.6 and the newer agent/team capabilities. A lot has changed recently, so I’d really appreciate fresh perspectives rather than links to older comparisons. My current observations: Claude (with Opus 4.6) seems extremely strong at deep reasoning and complex problem solving. Antigravity Ultra has the benefit of access to faster models (e.g. Flash), which can be very useful when paired with a solid plan generated by a stronger model. I care about real productivity in software development (refactoring, architectural changes, structured planning, multi-step tasks). I value agent-style workflows and long-context handling. Pricing is similar for me, so the decision is about ROI and workflow efficiency , not just cost. For those who are actively using one (or both) right now in 2026 : Which one feels more productive in daily dev work? How do they compare in terms of context stability on large codebases? Are there hidden limitations (rate limits, throttling, degraded modes)? Has Opus 4.6 meaningfully changed the value proposition of Claude 20x? If you had to choose only one today, which would you pick and why? Again, I’m looking for up-to-date experiences , not historical comparisons from before Opus 4.6 or recent Antigravity updates. Thanks in advance — detailed, experience-based answers are very welcome. submitted by /u/Physical_Concert_625
