I have two of the devices.
Onyx Boox Note3 10.3
Boyue Likebook Mars T80D 300 7.8
In general , if you want to browse internet on Eink devices, Onyx Boox series are much better choices than other brands (including Boyue), because it uses Qualcomm CPU, which is much faster than other brands, still, good for power consumption too.
Also, most of browsers are not customized for Eink devices (black&white only, slow on refreshing UI), the experience would be terrible using normal browsers on Eink devices. You can try to install EinkBro App, which offers better experience, and only takes 3MB in size. It's available on F-droid and Google Play Store:

You can have a look of a demo video that I took on Onyx Boox Note3, trying to use Onyx device's full text translation feature with EinkBro App while browsing web:
