Yandex Browser is a
freeware web browser developed by the Russian web search corporation
Yandex that uses the
Blink web browser engine and is based on the
Chromium open source project. The browser checks webpage security with the Yandex security system and checks downloaded files with
Kaspersky anti-virus. The browser also uses
Opera Software's Turbo technology to speed web browsing on slow connections.
The security features of Yandex are also mentioned
Yandex Browser - Wikipedia
IMO,
1) Both also use Chromium open source
2) Chrome takes your privacy data. For Yandex, the Russians take your privacy data. And with Putin's intention of building a Great Russian Firewall the encryption aspect in Russian software don't look good.
3) If you use a VPN then the security features of Yandex are of no use
4) If you use an AV then Yandex's Kaspersky AV serves only as a double-check on the downloads
5) If you use the Turbo feature with proxy (by Opera) then you cannot use your VPN
Maybe Yandex has better non-security features than Chrome but I'll still stick with Chrome for its fast update, familiarity and ease of use
