First and foremost, on a presentation front the games are incomparable. From the animations, to hit detection, to the character's sense of speed, weight, and locomotion response... Every facet of the two's presentation are worlds apart. When it comes to traveling through the world, in Spider-Man, zipping around the city is fluid, fast, and by reviewer and general sentiment, enjoyable. In Crackdown, the platforming is as good as ever, but driving is an absolute chore worse than the Batmobile in Arkham Knight.
When it comes to combat, Crackdown retains the lock on from the first one. You aim and hold down the trigger until the enemy is dead. There are several guns, but outside of some key, and very exciting standouts, they feel very similar. You can pick up objects on the ground and throw them, including cars as your agent is upgraded. All of this is done with zero reaction from the enemies you are killing, and there isn't very much in the way of enemy variety or memorable boss encounters. In Spider-Man, the enemy variety issue isn't much different than in Crackdown, but the game gives you dozens of gadgets and environmental traps to use against enemies in addition to the combat options pioneered by Batman and the earlier Spider-Man games. The similarities to Batman cannot be ignored, though Insomniac's title has a much greater focus on aerial combos and acrobatics, and the many gadgets keep things feeling somewhat fresh. The boss encounters in Spider-Man are typically presented as highly polished set piece moments.
When it comes to content, the comparison continues to be incredibly unfavorable to Crackdown. Spider-Man has an impressive narrative with excellent voice acting and writing that captures the essence of the source material, but with some missteps in the form of forced stealth sections and lame match 3 puzzles. Crackdown has a nonexistent narrative with mostly terrible voice acting and fairly rote boss encounters. For side content, neither game shines. Both have copy paste garbage side content that has been done better in dozens of games. A key difference is that Spider-Man's trash side content is underpinned by moment to moment gameplay that more people find enjoyable than Crackdown's dated offering. As for story mission structure, there is no comparison. Crackdown's story content is more akin to the bad side content of Spider-Man.
I'm not sure why people try to compare this clearly flawed game to other, superior titles. The game suffers for those comparisons. We have heard it compared to Doom, Spider-Man, and even Breath of the Wild, when it can't hold a candle to any of those titles and bears almost no resemblance to them. When I say that such comparisons leave me genuinely nonplussed, I mean it. I simply cannot see how someone who is thinking critically could fail to notice the yawning chasm of difference in the quality of every facet of these games.
A little off topic: Apologies for the late reply. I just got back from watching Alita Battle Angel with some friends. I found it to be a deeply flawed movie, with huge narrative issues and often subpar and stilted performances and questionable CGI on the eponymous heroine. I still enjoyed it, and had (oh no he is gonna say it) fun watching it, but that doesn't exclude its flaws and I would never compare it to the likes of Blade Runner even though they bear some resemblance to each other in subject matter.
