There are really no options outside of Element, unless you're a Linux user - then maybe you have a few ones.
All alternative clients on iOS, macOS, and arguably Windows are an absolute clusterfuck of UI/UX, broken features, and varying stages of completion. I say this as someone who wants Matrix to work: people need to demand more from client apps, and client apps need to stop being okay with barely hitting the bar.
Element also needs to set the bar, which I frankly don't think it currently does - but that's supposedly being rewritten, so I'm hopeful for what they produce.
