I like U-Locks better generally - I think they're stronger. But if I can only find a big object to lock to, then I will often use a chain. Chains are so heavy, I pretty much only use a chain for places I park my bike at regularly, so I can just leave the chain there locked up.
A good lock is just part of the solution. There is also how you lock the bike up - finding a good solid object to lock it to, making sure that the wheels are locked to the frame, etc. And then there is where you lock the bike and for how long and how regularly. If you park in the same place regularly, then a thief might see the pattern and study it to come up with a plan. Really, it is better not to park an expensive bike in the same public place on a regular basis! Really there is no perfect solution. You do your best but really nothing is totally secure.
Well said. To stop a thief, it's best to think like a thief to avoid one. Sorry about the link, it was meant for a lock + chain.
About the U-locks are very controversial. Even today at the shop a couple went to buy another new bike just for the reason of the use of a U-lock failed to be secure. The reason being is that they're easy to lock with either a Bic pen or a design flaw. Currently, the "fegettaboutit" kyrpt/chain lock & evolution 4 was found on youtube to be easily unlockable.
Take alboy finland locks. Sadly, some bugger made a concept video key lock CD on unlocking these things. It's a lock well known used by police stations, military, or industry protection. This key was made from England and has meters as you turn and pull down... Yeah, no lock is ever safe but I want a two locks to date to prevent theft slowing down persistant thieves.
I want the best of the best.
