We compared Fast ★★☆☆☆ with Google Fiber (original) ★★★★★ and concluded that Google Fiber is a better speed test than Fast.
This is mainly because Google Fiber scores higher than Fast in accuracy, data efficiency and speed.
The radar chart above is based on the results of our standardized speed test test. The results speak for themselves.
Strengths of Fast
By far Fast's strongest point is its usability. The speed test starts automatically, and has an interface that clearly shows one thing, namely the measured download speed.
In addition, you can easily pause the test. Furthermore, Fast is ad- and cookie-free.
It is therefore not surprising that Fast scores high on the list Usable speed tests and on the list Privacy respecting speed tests.
Strengths of Google Fiber (original)
Google Fiber (original) is accuracte and fast (which is a rare combination).
There are no ads and no cookies. Google Fiber is therefore a privacy-friendly speed test.
Despite the warning that "You are not on the Google Fiber network. Running a speed test on your mobile network may result in data charges" the Google Fiber speed test is data efficient.
Our recommendation
Based on what we know about speed tests, if we had to choose between these two speed tests, we would choose Google Fiber over Fast. The decisive factors are the high scores that Google Fiber achieves in the areas of accuracy, data efficiency, speed, privacy-friendliness and usability.
