Fossil Gen 5E vs Gen 4 Sport – Which is Better?
Although each of these two is a decent Wear OS smartwatch, the Gen 5E is a better smartwatch than Gen 4 Sport. With 1GB RAM paired with the 3100 chip it certainly offers a slightly better performance than Gen 4 Sport with a lesser memory. Moreover, the Gen 5E has a more premium build than Gen 4 Sport even though, the latter is a more befitting choice for sports activities, thanks to its lightweight design.
The Gen 5E has a loudspeaker that Gen 4 Sport lacks, as a result, you can make and receive calls directly from the Gen 5E via Bluetooth connection of a paired phone as well as play media files aloud which is not possible with Gen 4 Sport.
In other words, Gen 5E is a more comprehensive smartwatch than Gen 4 Sport which is a cheaper alternative.
