What is the best HO train set for a beginner?

Reviewers across r/modeltrains and YouTube unboxing channels consistently recommend a Bachmann ready-to-run set such as the Rail Chief, Santa Fe Flyer, Pacific Flyer, Thoroughbred, or Coastliner. They include EZ-Track, a DC power pack, locomotive and rolling stock, with a low enough price to learn on without a major investment.
