Well, there are multiple possibillities:
Sauroposeidon
Daxiatitan(cheater)
The French Monster(If it really is a front heavy sauropod as the anatomy indicates
Puertasaurus (though it really depends on its built)

All of these are quite fragmentary so we cannot have a definitive answer.

"Brachiosaurus nougaredi"
Amphicoelias fragillimus if it were to rear up (EDIT: I think I didn’t get that across well enough)

I thought about those, but I habe a few Probleme with them. The former may be a giant Titanosaurus oft Argentinosaurus size(massive but not overtly tall).
And the latter also has a problematic position, and diplodocoids dont seem to have the most flexible necks, which is consistant with their niche as grazers/low browsers.

Based on sufficiently complete material, I think Giraffatitan, at about 13m with fragmentary specimens approaching 15m tall, Brachiosaurus probably is in the same ballpark as well as Alamosaurus, Argentinasaurus, Puertasaurus and Daxiatitan, If the adult Sauroposeidon matches a full grown Giraffatitan in size, its long neck vertebrae will give it an edge in height, will it be 18m tall as originally estimated? that I don't know.

Well ths really depends on the morphology of specific fragmentary specimen. Several macroarians were very large and depending on exact outlook very tall as well.

• Nima Sassani’s skeletal of G. brancai (HMNS 2) is 22.5m long through the neural canal and 14.8m tall based on the scale bar, however the humerus seems to be ~1% too long in that restoration.
• EoFauna’s skeletal of the same specimen is 22m long and 12.8m tall, however the neck is less erect and if it was more vertical it would have probably have been considerably taller (adding the lenght of the neck in straight line to the height at the neck base gives over 15m).
• Paul’s skeletal is 22.2m long based on the humerus and 13.7m tall.
• Hartman’s skeletal is 23m long based on the humerus and 12.6m tall, again with a less erect neck (sum of straight-line neck lenght and height at base of neck=15.5m)

I knew Sauroposeidon was the tallest.

Let's not get into for-sure absolutes here people. But I think we can now feel confident saying that a genus of large brachiosaur was probably the tallest. Using such certainty creates unnecessary debating whether it be from actual height values (ex: 12 meters) or which dinosaur in question

"Brachiosaurus nougaredi"
Just heard of this dinosaur for the first time. I googled it and found this size comparison:

Could this be accurate? It's gigantic.

^120 tons is basically what seems to be one of the upper weight estimates for amphicoelias, which was HUGE. I doubt any brachiosaur would even come close to that

@Spartan
Not accurate, Brachiosaurus altithorax itself has a very small sacrum for its body size compared to other large sauropods, despite Lapparent's referral to Brachiosaurus, there's nothing that suggests "Brachiosaurus" nougaredi is an actual species of that genus making isometric scaling like that probably wrong.

For a comparison of how sacrum length can vary between sauropods of different sizes, Argentinosaurus (60+ tonnes) has a sacrum just a little longer than that of Apatosaurus louisae (~20 tonnes)... though, one might argue that Argentinosaurus and Apatosaurus are fairly distant.

I don't know but the picture is right. Tyrannosaurus was definitely not the King of the Dinosaurs.
Judging from the fact that Brachiosaurus Nougaredi existed during the Cretaceous period, according to recent studies, and from the fact that, just like someone here said Brachiosaurus had a sacrum quite too small for its body, I would say that Brachiosaurus Nougaredi might have been a titanosaur like Paralititan, which also lived in Africa during the Cretaceous period.
