Data notes and caveats
This video splits its verdict by surface rather than crowning one overall winner: LLPT (cheapest at 22 cents/ft) won both wood tensile and wood shear tests ('LLPT did just that on both the wood tensile strength as well as the wood shear strength'), while 3M won the steel shear test and the closing line frames that as the decisive win for smooth surfaces ('regarding a smooth surface such as steel, 3M just couldn't be beat, clearly winning the showdown'). Treated as winner:null per the per-use-case-favorites rule rather than forcing a single winner; budgetPick captures LLPT's explicit best-value framing. The video description's Products Tested/affiliate-link list only names 6 brands (XFasten, Duck, LLPT, Loctite, T-Rex, Gorilla); 3M, Gorilla Clear, and Fix Pro are absent from that list despite being fully tested with consistent data across all three tests (3M and Gorilla Clear are named in the video title, so this looks like an incomplete description rather than a transcript error). Duck's claimed rating of 'up to 3 lb' is roughly 10x lower than every other brand's claimed rating and is flagged as a possible dropped caption digit, not corrected.
