What does strength have to do with anything (Don't answer that 🙂 )
Spider-man's fighting style encorporates agility, speed, his awesome reflexes and his witty jokes. Personally I couldn't care for sh*t about his strength. Sure it's good to see him doing some awesome things, but IMO Sider-man isn't about strength. Exactly why I'm more comfortable with Ult.Spider-man. He's not supposed to be this car throwing big muscled Hulk wannabe..
His strenght should be above ANY Normal human being (including those peak humans, like Wolverine and Cap) He shouldn't have big muscle either.. It helps to create the illusion that he's supposed to be an average guy while not fighting Venom and Octopuss*.

Besides, his strength doesn't propably matter at all since he'd be propably holding back against Galactus too. Only way to make a fight "realistic" would have the opponent say "After you, I'm going to kill your wife and aunt!!!11" Imagine Cap saying that 😘
