I've been using it for the last 5 or so years with no real issues (Linux, Windows and Android). I'd say the Android one is probably the weakest link but still usable and of course having ad-block on mobile is a huge quality of life improvement. Other than that I don't notice any slowdowns compared to Chrome, the UI is very similar anyhow and the addon ecosystem is decent too.
