The quick take
The short version of why each pick lands where it does, built straight from the measured results.
“so which ratchet is the best and the Ula tools dominated The Showdown with an average finish of 4.8 it's a very good ratchet and and offers a complete package”
Placed top three in 2 of 4 measurements.
Best in 1 of 6 measurements, including Tight space arc swing.

(tied 2nd best with Nepros, behind Wera)
- 2GearWrench 90 90 tooth
less than 1/10th of an inch (no exact figure given, better than average)

garbled in transcript ("almost a[?] inch of slop"), a fraction digit was dropped by captions
- 4DeWalt0.03 in
described as 90 percent less slop than Duratech

Directional switch force (grams)
- 1Olsa Tools589 g
described as a little stiff
- 2GearWrench 90 90 tooth238 g
- 3Duratech338 g
(about 3/4 lb)
- 4DeWalt788 g
(1.7 lb), described as very stiff
- 5Crescent204 g
described as very easy to change directions; confirmed again in the category recap sentence
- 6Kobalt 81747322 g
about the same as Duratech
- 7ICON297 g2nd
2nd place behind Duratech
- 8Tekton588 g
described as pretty stiff
- 9GearWrench 120XP 120XP199 g
moved into the lead, later tied with Wera per the category recap
- 10Wera199 g
tied for the lead with GearWrench 120XP per the category recap, described as easy to rotate
- 11Craftsman396 g
the transcript literally attributes this reading to 'the Crescent' a second time, but Crescent's directional force was already given as 204 g earlier and reconfirmed in the same category's closing recap sentence, and this second mention falls in testing-order sequence right after GearWrench 90, exactly where Craftsman belongs; reassigned to Craftsman per testing-order resolution, flagged here
- 12Stahlwille263 g
described as pretty easy to work with
- 13Mac Tools488 g
- 14Snap-on534 g
- 15Nepros829 g
the worst result in this category, described as really struggling
- 16Proto
transcript garbled as "48", almost certainly missing one or more digits given every neighboring value is in the 200 to 830 range; likely intended around 480 g, kept verbatim, do not guess the exact figure
Failure load (ft-lb)
- 2GearWrench 90 90 tooth276.50 ft-lb
- 4DeWalt269.50 ft-lb
drive failed at the 3/8 in drive point
- 5Crescent
transcript says 22.8 ft-lb, which is roughly 10x lower than every neighboring result (160 to 300 range); almost certainly a dropped caption digit, likely intended as 228 ft-lb, kept verbatim, do not silently correct
- 6Kobalt 81747
transcript garbled as "169 5 foot lbs", likely 169.5 ft-lb; weakest failure result recorded up to that point in the video, attributed to its very compact size
- 7ICON287.4 ft-lb
moved into the lead for torque strength at that point
- 8Tekton
transcript garbled as "2658 ftlb", almost certainly 265.8 ft-lb with a dropped decimal point given every neighboring failure value sits in the 160 to 300 range
- 9GearWrench 120XP 120XP
transcript reads "27 7.9 ftlb" (stray space), read as 277.9 ft-lb
- 10Wera
transcript garbled as "2561 ftlb", likely 256.1 ft-lb with a dropped decimal, let go a little sooner than average
- 11Craftsman
closing leaderboard recap states Craftsman came in on top at 295.2 ft-lb (highest of all 16); the mid-video failure segment itself is internally inconsistent, reading 'snapping at 295.27 at 279.50 ftlb' in the same sentence, both figures recorded here, flagged
- 12Stahlwille
transcript says 22.2 ft-lb, roughly 10x lower than neighboring results in the 160 to 300 range; almost certainly a dropped caption digit, likely intended as 222 ft-lb, kept verbatim
- 13Mac Tools206 ft-lb
described as giving up a lot sooner than expected, and its handle pivot pin broke and the handle bent
- 14Snap-on292.50 ft-lb
in the failure segment; the closing recap states 292.00 ft-lb for Snap-on, a minor discrepancy, both figures recorded
- 15Nepros231.50 ft-lb
described as failing a lot sooner than most of the competition
- 16Proto263.50 ft-lb

How it was tested
- tight space working arc swing (back and forth passes needed for one full 360 degree rotation within a 30 degree space)
- handle to ratchet head slop / build construction (dial indicator, inches)
- back drag (fishing line and scale, grams of resistance)
- directional switch force (grams of force to change direction)
- head size / compactness (side to side and front to back, mm)
- failure load under torque (ft-lb until the ratchet broke)
