Spiderman will get driven into madness dealing with Gotham city, IMO.
He gets already pushed mentally dealing with guys like the Osbournes and Kraven.
Dealing with the madness of the Joker, Szas, Killer Croc, Two face, Ventriloquist, The Mad Hatter, Dr. Freeze (just to name a few), they are not your regular criminals with superpowers, like the Vulture, Shock, Rhino, most of the Batman criminals are straight up psychos that need to be in a mental institution, not in a prison.
When it comes down to the level of crazy that Batman has to deal with in Gotham city vs dealing with the level of crazy of Spiderman's villains, there is basically no contest and if Batman's own sanity gets pushed by Gotham city, Spiderman's most surely will get trumped by it, IMO.
