No, he does have limits. There were plenty of times where Superman needed help lifting certain things, ergo, he's not unlimited. He needed help moving Brainiac's planet sized ship, needed help from Wonder Woman and Kyle Raynor to lift Spectre, and didn't even really lift that supposedly infinite book in Limbo because as soon as it left the pedestal and its stasis feild by him sliding it off, it dropped from his grip and read itself. Also, as far as lifting Spectre, there's two things wrong with Death Battle's idea that because he was lifting Spectre, that he can lift infinite weight. First off, if he can lift infinite weight, then why did he need both Wonder Woman and Kyle Raynor? If he can lift infinity, then he shouldn't need help to lift something infinite. Second, if he can lift infinite weight, then why would heroes like Wonder Woman and Kyle Raynor be of help? They're both noticably weaker than him.



As for various speed stuff. Well, in DBSuper, Goku was able to get quite a few punches on the assassin known as "Hit" a character who is able to jump through various points in time in order to get the drop on his enemy and even without that, had speed comperable to Goku. Being able to even keep up with a guy who can use time itself to dodge outclasses any ftl speeds.



As far as strength, well, in the DBSuper manga, his first fight with Beerus in his first god form is quoted as shaking the whole universe. I.e. each hit from either character caused everyone and everything to feel the shock of each impact from both characters. Don't ask me how multiple shockwaves that were powerful enough to spread to all corners of the universe with just as much power didn't cause all the planets to crumble. Both DC and DB are guilty of having their heroes do things that are against the laws of physics, such as being able to hit a guy who uses time jumping to dodge and attack, making his moves instantaneous, yet Goku was still able to get a few hits on him; despite Hit upping his game by jumping to even more random points in time in various locations and positions.



The equivalent of going faster than an instant is comparable to Flash level of physics defying speed. Which Flash actually did in one issue where he went faster than an instant by beating god-like beings in a race who could make it back to earth in an instant by teleporting. Flash got there faster than an instant. Literally no time passed between the race's start and Flash somehow getting there faster than 0.0 seconds, i.e faster than an instant. Goku was able to get a few good punches and kicks in on Hit, who used time jumps to INSTANTLY dodge any attack and put himself in a position to attack from any angle, also instantly and combine that with the extreme speed he has outside of time jumps. However, Goku was able to counter a lot of those, even some attacks that Hit made pretty much instantaneous with his time jumps. I.e, Goku demonstrated Flash level reflexes, if not speed.



Sorry, but being quick enough with reflexes to counter some of the moves of a guy who uses time to move instantaneously out classes any faster than light speed that Superman has and being able to shake the universe with punches in just his first god form out classes pench pressing a planet for five days.



Plus, there's the fact that Goku can use Kaioken in conjunction with SSB to multiply his power past universe shaking levels.
