I'm talking about Neon, which is by far the most effective way of getting around in the game. Smoke, Video, and Concrete have their "quirks" in how you can get around faster, but despite Smoke being the best-designed around actually looking at your surroundings, it's the slowest even at its top "speed". Video lets you fly as you mentioned, but still is not as effective as Neon, and in terms of being aware of your surroundings, with Video you only ever have to watch out for where satellites are. Compare this with inFamous 1/2 where there's a myriad of different options and things you need to watch out for in order to traverse at your fastest. Concrete grants you top speed with the running and "wheel" ability but does not require you do anything but avoid obstacles. The float lets you levitate for very long periods of time and lets you actually get higher, but again, nothing that relies on where you are in the city and its effectiveness does not rely on the game's world geometry.
Neon, as I mentioned before, is simultaneously the fastest way of getting around and the worst way of getting around as a gameplay mechanic that the series has had so far. You press O and you're instantly at top speed regardless of where you are. The launch lets you move vertically, but then again so does the wall run. I can't tell you how many times I attempted a long jump to another building, missed the jump by a bit making me land on its side instead of its top, and then immediately thought "well that's OK, the wall run is about to nullify that in a fraction of a second". The more I played the less I cared about what I was doing to traverse the area, because the mechanics of Neon auto-corrected any failings. I stopped even wondering if I was going to make the jump I was trying to make. Jumping from building to building is in no way faster than jumping off a building and running along the street (it is made faster with the boost "pads" in the DLC, which provided some very badly needed interaction with the world you're traversing, but the "pads" in question are plopped into the world with no real consideration as to how they should exist in that world. The traversal continued its existence "in parallel" to the world you were traversing).
If we contrast this to SO or even previous inFamous games, the world IS what you traverse. It isn't something for you to "hop over" (in your words), but rather something for you to traverse
through. You jump Cole or the Sunset Overdrive protagonist off a power line and you immediately start thinking where to go next. What is near you, how far it is, and if it'll maintain your momentum the way you want it to. You don't have the luxury of jumping ridiculously high by pressing O and then X on a whim. This deliberate limitation is something that is a careful balance between supernaturally fast traversal and something that has limitations on its own. Being able to climb a building with neon, regardless of its ledge design, regardless of its shape, height, or anything that is attached to said building, is the biggest gameplay regression of Neon as a traversal device. Literally the only option devices you have are "run fast", "jump high", and "wall run". Since "wall run" is identical in form and function to "run fast" (you're still pressing the same button and holding the same direction), "jump high" is the only other option. It vastly oversimplifies the way you run through the game and it is all the poorer for it. Had the game given us some reason to use any of the other powers for traversal there would've been a reason to go back to Smoke and enjoy the car jumping, vent searching, exhaust gliding goodness.
(I still like the game a lot, but this critique of Neon is something I'm not seeing very often and something that really struck me as I was playing during the game's launch.)
They really are. Both series are some of the most mechanically interesting IPs I've played, mostly because they take existing formulas and twist them to fit something very particular (inFamous making you a superhero, SO wanting to make this cross between Ratchet & Clank, Tony Hawk, and a bunch of other things).
I don't mind people just dropping their two cents on which they think is better. Not everyone's as interested in picking the games apart as I am
