head to head
The Jackbox Survey Scramble asks more than Tabletop Simulator, and the gap is variance.

Reads · Bluff & Deduction
A physics sandbox whose actual skill test is whatever board game you load into it.

Variance · Bluff & Deduction
A party game testing guesses about how a crowd answered survey questions.
Tabletop Simulator leans Reads (Bluff & Deduction); The Jackbox Survey Scramble leans Variance (Bluff & Deduction).
The Jackbox Survey Scramble leans a little harder on execution, though the gap is small.
Tabletop Simulator
Fiddly physics manipulation, never a skill ceiling
The Jackbox Survey Scramble
Quick answer entry, minimal dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Tabletop Simulator
Depends entirely on the tabletop game played with humans
The Jackbox Survey Scramble
Guessing what the crowd answered involves modelling people
The Jackbox Survey Scramble leans clearly harder on variance.
Tabletop Simulator
Dice and shuffled decks supply whatever randomness the game has
The Jackbox Survey Scramble
Hidden survey results drive the guessing each round
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Tabletop Simulator
Strategy lives in the hosted game, not the simulator
The Jackbox Survey Scramble
Knowing common-answer patterns gives a small edge
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
