The number that decides this comparison
Forget the headline ratings for a second, 8.8 for the Fastarc G-1 and 8.5 for the Quantum X Pro. The gap that actually matters between these two rubbers is throw, where the Fastarc G-1 scores 8.5 against the Quantum X Pro’s 4.8, a delta of 3.7 points. That is by far the largest swing on any axis in this pairing, and it is not a small stylistic quirk. Throw describes how high and forgiving the ball comes off the rubber, and a gap this size is the difference between a rubber that will carry a mistimed opening loop over the net for you and one that punishes a loop struck a fraction late or a fraction low. If your game depends on lifting backspin from a couple of steps back off the table, this single number should end the debate before you even weigh anything else.
Where the two are close enough not to matter
Not every axis here is decision-relevant, and it is worth saying plainly which ones are not. Tackiness sits at 2.5 for the Fastarc G-1 and 3.0 for the Quantum X Pro, a 0.5 gap on a scale where both rubbers are firmly in non-tacky, tensor territory. You will not feel that difference in a rally. Durability is similarly close, 7.0 versus 6.4, a 0.6 edge to the Fastarc G-1 that is real but modest, not the kind of gap that should override a fit decision made on throw or playstyle. Control is a genuine but secondary factor: 8.0 for the Fastarc G-1 against 8.5 for the Quantum X Pro, a 0.5 edge to the Tibhar sheet that lines up with reviewers at TableTennisCoach and BladeRubber praising its low sensitivity to incoming spin, useful for blocking and countering rather than for generating your own arc.
What the rubbers are actually built to do
The Quantum X Pro is not a worse all-court rubber than the Fastarc G-1, it is a different tool. Reviewers cited on Revspin and Reddit describe it as excelling on the backhand off carbon and composite blades, with low sensitivity to spin that makes blocking and countering unusually reliable, and it is the rubber used by professional player Bernadette Szocs, a real signal of its ceiling in a near-table, counter-topspin role. But its own listed cons are explicit that it “struggles from mid-distance and far-from-table play” and is “built for near-table aggression.” That is consistent with the low 4.8 throw score. The Fastarc G-1, reviewed at Tabletennis11, Megaspin and Racket Insight, earns its reputation the opposite way, as a forgiving, high-arc, all-court attacking rubber for either wing that Nittaku itself markets as fast with an arc, and reviewers back that up with Tenergy-class durability at a lower price.
Should you switch
If you already play with the Fastarc G-1 because you need a safety margin on opening loops against backspin, moving to the Quantum X Pro is a downgrade on exactly the axis you rely on, a near four-point drop in throw is not something technique alone compensates for quickly. The switch makes sense in the other direction only if your actual problem is backhand consistency on a carbon or composite blade, where the Quantum X Pro’s control and low spin sensitivity are the documented strengths, and you are willing to trade some of the Fastarc G-1’s forgiving arc for a flatter, more direct near-table game. If you play mostly forehand loops from mid-distance, this rubber will feel like it’s fighting you.
Bottom line
Pick the Fastarc G-1 if your game lives on opening backspin with a big, safe arc, on either wing, and you want Tenergy-like durability without the Tenergy price. Pick the Quantum X Pro only if you specifically need a near-table backhand weapon on a stiff blade and you already have the technique to compensate for a much lower throw. The 3.7-point throw gap is the whole story here; everything else is secondary noise by comparison.
Frequently asked questions
What is the single biggest difference between the Nittaku Fastarc G-1 and the Tibhar Quantum X Pro?
Throw. The Fastarc G-1 scores 8.5 on throw against the Quantum X Pro's 4.8, a 3.7-point gap that is the largest difference on any axis between these two rubbers, and it directly affects how forgiving each one is on opening loops against backspin.
Is the Tibhar Quantum X Pro a good upgrade from the Nittaku Fastarc G-1?
Only if your priority is backhand consistency on a carbon or composite blade. On raw axis data it trails the Fastarc G-1 on throw by 3.7 points and on spin by 0.8, so players who rely on lifting backspin from mid-distance will likely find it a step backward, not an upgrade.
Does the tackiness difference between these two rubbers matter in play?
Not much. The gap is only 0.5 points (2.5 versus 3.0) and both sheets are non-tacky tensors, so this is not a meaningful factor in choosing between them.
Which rubber is better for a beginner?
Neither is really built for beginners. Both are described in reviews as suited to intermediate-to-advanced players with a committed, technically sound stroke; the Fastarc G-1's cons note it needs a technically sound stroke to reward its firm 47.5-degree sponge, and the Quantum X Pro's cons state it requires decent technique to reach its potential.
