Bottom line

The verdict

Google Antigravity edges out Sudowrite by 0.7 points (8.0 vs 7.3) -- a A-tier vs B-tier split that's narrow but real. Not a blowout; both belong on a shortlist. The score gap shows up most clearly in the categories that matter for Google Antigravity's strengths, so if those categories are your priority, the lead translates.

On pricing, Google Antigravity starts free while Sudowrite requires a paid plan from day one ($10+). If you're testing the waters or running an occasional workload, that gap matters more than the score differential. Sudowrite starts at $10; Google Antigravity starts at $0. Compare what each entry tier actually unlocks before you compare list prices -- the limits matter more than the headline number.

By use case: pick Sudowrite when fiction writers who want an ai co-pilot that understands narrative, not just grammar. Pick Google Antigravity when developers working on large, multi-file projects who want to parallelize their workflow. The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap. If you're squarely in Google Antigravity's lane, the tier-list ranking and the use-case fit point the same direction; if you're in Sudowrite's lane, the score gap matters less than the fit.

Bottom line: Google Antigravity is the safer default for most readers, but Sudowrite is competitive enough that the tie-breaker is your specific workload, not the spec sheet.
