Exactly, as I said, lessens the effect, not talking about pixel peeping, Look at the pic of the train, which "looks" sharper to your eye, looking at the pic as a whole??? Ask a group of people which looks better, Your pictures prove exactly what I'm saying, there is a nice sharp edge at the front of the train, your brain sees this and sees the image as being sharper and more detailed. We are actually agreeing about this, but my comment are more based in what people see, not what happens at a pixel scale.
Beyond the technical reasons, There is also "real world" applications and circumstances that "facts and figures and pixel peeping" dont take into account. What is the first thing 95% of people in front of your camera do the very moment after you take a photo?....Move......And as a photographer you need to do what little you can to control whats happenning infront of you to get a greater success rate. That very moment that flash fires, people assume the photo is taken and its over, they unconsiously relax their pose, some People immediately turn to talk to the person beside them, some people uncontrolably"flinch" after the flash as a result of the flash itself (even when they know its coming), groups of people move and stop posing, some people are even walking away (even when you explain what you are doing and ask them to say still!!!) Babies turn and stare at where the big flash came from, some animals run, some birds fly off, These are all things you as a photographer have little to zero actual control over, So if you are using Leading shutter, your flash fires yet you've still taking the photo for the next half a second or so, up to 5 ,6 or even 10-30 seconds, you will get more blur in your photo than with trailing shutter, where the bulk of your exposure is done with subjects remaining still until the exposure is over the millisecond after the flash fires, so any resulting movement of your subject caused by the flash firing is not captured, thus increased success rates and sharpness (less blur) for photos, so effectively Trailing shutter sync as a technique can increase sharpness and help reduce blur over leading shutter sync as a technique when applied to these kinds of photos. Leading and Trailing shutter sync is not just about the mechanical relationship of the camera and flash , but everything as a whole, the camera flash setting is just a part of the Technique not the whole technique. In photography, using a good, tried and tested technique to help increase keeper rates and in some cases ensure a one time only oportunitity has the most chance of success, is not a bad thing.
I'm sorry, but all too often people are too quick to jump up and tell others on the internet they are "wrong", and I could have made a better answer that to come back with a retorical "No... Actually" to somebody saying "It won't, Actually", but thats the internets for you, and I'm sorry about that. Arvh's explaination of how to get the exposure settings was absolutely correct, I was just adding an extra tip to help achieve a good result, what I'm unsure about is why I was so shouted down and questioned so strongly by multiple people and had sample pictures thrust up in evidence of just how "wrong" I was (pictures that demonstrate a completely different application of the technique as well), for simply offering up an extra helpful tip when doing this kind of photography. As far as I'm concerned there is not a "wrong way" with leading or trailing shutter sync, but just what a person decides to use to produce the particular photo they are trying to achieve, to make that deciession they need to understand which will suit the particular application better. Only knowing that you turn a switch to set a camera/flash to a particular setting is only part of any technique, knowing why you do it and choosing when to use it and how it affects everything around you (not just the camera/flash) it's about applying skills.
So getting back to the OP's original post about not knowing about this kind of flash photography and getting a correct exposure reading for the background then using fil-flash, not motion based blurs with frozen subject, but, using longer shutterspeeds and fill-flash to achieve cityscapes with people infront with little to no blur at all, using trailing shutter sync is a safe place to "start out" to help get a good rate of keepers.
