D lock generally lighter for the same level of protection. The 8/10mm links of chains will generally yield to 4' bolt croppers. 16mm+ dlocks (also abus's 14mm square profile) will generally need an angle grinder.
On the flip side, if you don't fill the lock properly, dlocks are vulnerable to jacks etc and chains are a bit trickier to angle grind.
Mostly of course it's about not leaving expensive bikes locked outside!
4" ??
4' bolt cutters, about £30:
Leverage of course increases with length, but at 4' they're getting pretty hard to conceal. It's worth playing with some big ones if you want to understand what security you do and don't have. Ditto an angle grinder,

Looks more like a 24" set -- but how they're measured isn't the issue -- I have used large 3 foot bolt cutters to cut 8mm and 10mm galvanized chains on sprinkler systems but I know this wouldn't cut the same link if it was a higher grade of chain. What do you think of the kryptonite chains.
I think whatever lock it is it needs to be practical or I'd end up not using it or just not able to go into any shops etc.
Currently I use a heavy stainless cable type combination lock. You'd need a very expensive cable cutter to cut through it. We use a £200 cable cutter at work to cut stainless earth cable but that will only just about cut 10mm square ( not diameter -- there's a big difference ) my lock must be at least 50mm square cable. I find it very easy to use.
I'm only shopping or eating in cafes so not left for long periods of time. When I'm camping it'll be around a tree near my tent -- couldn't do that with a D lock.
I am here. Where are you?
