All this talk about this lock vs that lock to secure a bike is based on the premise that one lock has merits over another in preventing theft. While that may technically be true, actual security has to do with the how high of a hurdle a thief must clear to accomplish his goal, whatever that may be.

It is not the goal of every thief to steal a bike. Some may need just a saddle or seat post. Some might simply want the fork, or bars, or shifters. Others might just want a wheel.

A thief with only the most rudimentary knowledge of bikes can do a lot with no more than a 4,5, & 6mm Allen wrench & a 9/10 mm combination wrench.

In only a minute or two a motivated opportunist with the above listed tools can still make off with the fork, seat post, pedals, crankset, derailleurs, handlebars, & super awesome set of brifters, but the overall package of a suite of locks suggests it's just easier to invest effort elsewhere.

I've seen it all. A lock is about your feelings of security, not the bikes actual risk.

IME the only sufficient deterrent is 3 U-locks & a cable lock.
Meaning:
1 U lock trough the front wheel to the frame/rack.
1 U-lock through the rear wheel to the frame/rack.
A third lock locking the frame to the bike rack.
Finally, a cable lock through the saddle rails & seat stays.

Lastly, you can further skew the risk/reward equation by using a bike of lower value (perceived or actual.)

My kids 100% mechanically sound but ratty looking, sticker covered, & rusty 1985 Peugeot Montreal Express was locked as above 40 hours per week in front of a grocery store in a known high crime area & another 10 hours per week on an adjacent college campus. In spite of several thefts every month from the very rack he attached his bike to, the only incident of note for him was a missing headlight/taillight the one day he was complacent.

Only stupid idiots leave a valuable bike & dumber stupid idiots think a lock means security.

I once stopped for lunch at a picnic table during a ride & watched a guy in a pickup truck curiously break out a lawn chair & stake out a Port-a-potty by the bike trail. His stake-out only lasted as long as it took me to eat my pb&j sandwich. He succeeded. In only seconds the bike was in the back of the pickup, & the poor fool with the full bladder had a very long walk ahead of him.
