These two barely overlap. The Fastarc G-1 is a premium tensor that pairs heavy spin with real speed and a high, forgiving throw on opening loops, made for intermediate-to-advanced attackers on both wings and built to last. The Mercury II is a five-dollar tacky Chinese rubber with very high control, genuine grip and a forgiving, elastic sponge that suits beginners, all-round players and choppers.

The gap is performance versus accessibility. The Fastarc G-1’s firm 47.5-degree sponge rewards a committed, technically sound stroke and is too much for beginners. The Mercury II is slower than tensors, especially at distance, and its medium throw can clip the net on passive shots, but it is far easier and far cheaper.

Buy the Fastarc G-1 if you are a developed attacker who wants speed, spin and durability and can drive a firm sponge. Buy the Mercury II if you are building a first racket, want a control-and-spin all-round or defensive sheet, or simply want a serious tacky rubber for almost nothing.

The Fastarc G-1 by a clear margin — it offers real attacking speed with spin, whereas the Mercury II is a medium-paced control rubber that slows at distance.

Is the price difference justified?

For a committed attacker, the Fastarc G-1 earns its cost with speed, spin and long life. For value-seekers and improvers, the Mercury II is hard to beat at around five dollars.
