I downloaded the browser, got pestered to invest in cryptocurrencies, then deleted it.
I don't get the ads and the pestering as mentioned.
One annoyance is the default to reopening the same tabs when restarting (mostly from cache), but that can be easily changed in settings.
Apart from that, the browser is fast and seems to work just fine for me.
