I like this tool by Shimano - very durable (you need a 32 mm socket/wrench to "operate" it):
TL-UN74-S

The good thing about its design is I can easily put some spacers (if the axle is so long it protrudes when the tool is put in place) and washers to keep it in place using a square taper crank bolt.
That helps a lot when starting to unscrew some very stuck bottom brackets.
