Both cover HTTP, HTTPS, and both sit in the protocol and API load tool bracket. 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 Artillery against Tsung. Run the same scenario on both before you standardize; the rows below only tell you what is true on paper.
