Huawei's security doesn't come close to Cisco's security practices. Mostly because the vast majority of their hardware and software was sourced from stolen IP (Huawei had cash bounties for employees to provide stolen IP to the company). If you sell stolen technology, you don't truly understand how it works or how to secure it.
Given the choice, I'd choose Cisco every day of the week. It's not perfect but then again there's no such thing as perfect security.
With an E2E messenger, you can be sure that most likely your communications are not being intercepted. With a Chinese company, your communications are never secure.
Not only are Chinese software products not secure, but they'll lie to you about their security. Zoom claimed to have E2E encryption on calls which turned out to be an egregious fabrication (on top of them exporting calls to Chinese servers).
