Both have a free tier, so you can try either at no cost before committing.

What is QuestDB best used for?

QuestDB is most often used for time-series analytics ingesting up to 20m rows/second from iot sensors or financial data feeds, real-time dashboarding with 32ms time-to-first-row latency for minute-level analytics, applications requiring multi-tier storage (hot ingest, real-time sql, cold parquet archive). Of those, time-series analytics ingesting up to 20m rows/second from iot sensors or financial data feeds and real-time dashboarding with 32ms time-to-first-row latency for minute-level analytics are not what Refact is typically brought in for.

What can QuestDB do that Refact cannot?

QuestDB covers High Throughput Ingestion, SQL Support, Time-series Optimization, SIMD Vectorization. Refact covers Autonomous agent workflows, IDE chat, Real-time code completions, GitHub integration.
