Actually they are all the same - the difference is - one style is OEM Briggs (in the shape of the Briggs logo) - the others are made in taiwan aftermarket "double duty" (notice there's 4 outer holes instead of 2 - they do duty as two different sizes, where with the Briggs pullers, they are sold separately)
- there's actually 4-5 different briggs flywheel pullers, and one of them costs over $125.00 dealer cost. (just got one this spring)
But the aftermarket ones, there's just that one style that covers 2 Briggs part numbers - one's for the smaller size flywheels, commonly the ones used on lawnmowers the other for the heavier size 8 HP engines But when it comes to OE Briggs, there's the pullers for the bigger Intek and Vanguard engines, special new pullers for the new DOV's and pullers for the Micro Engines..
We are actually one of the vendors in that list on ebay selling the Oregon version of the made-in-taiwan puller - most of the briggs OE ones look to be "New Old Stock" - they're pretty durn cheap - which is why I don't list them on our ebay store - cant compete and remain profitable at those prices. Actually looks like a whole bunch of them are selling Stens versions and just drop-shipping them using Stens stock photos.. which works.. until they start getting backordered at Stens.

Oh yeah - as to which I prefer - have used BOTH (among others) and nothing, but nothing beats the OEM Fit and Quality.
