Both run a firm 47.5-degree sponge with a high, safe throw and work on either wing, so the gap is in ceiling and price. The Fastarc G-1 is the higher-rated rubber, combining heavy spin with real speed and Tenergy-like durability that drops off slowly. The Rakza X matches the high throw and adds outstanding grip that overrides incoming spin, with a linear, easy-to-control response, at a mid-range price around 50 USD.

Choose the G-1 if you want the higher-performance, more durable option for top spin and speed and have a committed stroke. Choose the Rakza X if you want strong grip and a predictable, controllable feel that excels on loops and counter-topspins for less money, accepting it is weaker for passive blocking.

Both reward sound technique and a full swing. The G-1 is the premium all-court attacker, the Rakza X the value-grip loop specialist.
