Yup, there are several options... And I guess, as everything, it's a matter of taste. I do believe Tox shouldn't be used when looking for privacy and security, and somehow, perhaps due to lack of developers, that hadn't changed for quite some time. FYI, there's a Briar for gnu+linux, though I can't tell if there's a desktop version of it (I do know ubuntu touch makes it available for phones). Unfortunately I don't like status.im, it includes a crypto wallet within, and though it's OSS, it's not FLOSS, which I prefer, having an option. I'm hopping for Jami to get more polished, both on the devices syncing and the UI. I have to see what happens with Briar for gnu+linux, and although I lost hope some time back, I'd really like Tox to improve on its security status. BTW, I used Tox (I really had high hopes on it), and there's no multi-device support. On Android I used both, trifa and antox (it seems antox has been dropped now a days), and on desktop I used qtox. And with no exception, on Android, tox apps, briar, jami, all are power hungry, which is the other thing I'd really like them to improve, but have low expectations given their p2p nature...
