I've never used WhatsApp, can't really compare. But we—team of ten tech-savvy persons—rolled back to Telegram in three days after trying RiotIM. Manual E2E keys sharing in Riot is not perfect, but definitely better than the lack of E2E at all in Telegram, however Linux desktop and especially Android performance was dreadful. At least that was the state at the beginning of the summer of 2017. How long do you use Riot? Can you confirm there have been significant changes since 2017Q2?
