Woodturner's Chucks (updated November 2018)
Chucks are threaded to match the lathe, either direct threaded or with the use of a threaded insert. The insert converts the chuck to fit the lathe.
The insert shoudn't be confused with an adaptor to change the lathe threads.
Thread adaptors from small to large generally don't overhang the lathe spindle however adaptors from large to small (exerts) have to by necessity.
Chucks for woodturning generally work on the scroll principle where the jaw carriers are moved in & out concentrically by a spiral of metal.
The carriers must engage the scroll in the correct sequence. This is normally 1234 but I have had one chuck where the sequence was 2143 - presumably because the jaws were wrongly number stamped.
Jaws attach to the carriers (sometimes called inserts) with machine screws. It doesn't matter which jaw fits to which carrier but it makes sense to match the numbers (I'm not aware of any where it does matter).
The most common size for the main body is 95-100mm.
Some older chucks are operated by levers rather than a key, which requires a little more dexterity.
Hex or square chuck keys are easier to locate than fluted keys
Stepped jaws are not meant for wood. If you have no other option support the outboard end of the piece using the tailstock.

If we agree that they all do what they are supposed to do, then it all comes down to ease of use, value for money, availability of jaws & the ability to move it to another lathe at a later date.
As a solid chunk of metal, a woodturning chuck will take nearly everything that a turner can throw at it, but that's not to say that it can't be broken with brute force (& perhaps some ignorance).
All the comments are my personal opinion.
