Curator verdict
Both cover HTTP, HTTPS, WebSocket. Recorded protocol coverage is the same width on both sides (5 protocols), so breadth is not the deciding factor here. Team language and existing tooling usually settle Gatling against Artillery. Run the same scenario on both before you standardize; the rows below only tell you what is true on paper.
