Quick Answer

Pipe insulation and heat tape solve different halves of the frozen-pipe problem. Insulation slows the freeze — it buys hours. Heat tape prevents the freeze — it costs electricity all winter. For most homes the answer is insulation first: it’s a one-time, no-operating-cost purchase that handles every pipe that only occasionally sees freezing conditions. Heat tape is the right tool only for the specific run that freezes every single year — well lines, crawl-space feeds, north-wall pipes, mobile-home supply — and for those runs, the gold standard is both: cable on the pipe, insulation over the cable.
