Different POV:
I work on large Matrix-based state infrastructure which includes collaboration with Element. In my experience their team has integrity and is competent, though the UX aspects of especially Element X could progress way faster. Imo this is in part due to the fact that their key customer segments are no longer private individual users but rather large public bureaucracies in Europe going after digital sovereignty.
Imo the key point is: You are not choosing Element but Matrix. Element is just the most well-known of many client-side messengers implementing the open standard Matrix. While Element is very active in the Matrix foundation, they cannot unilaterally change said standard.
Imo moving to matrix is a great move for personal sovereignty, even if the protocol itself is at times a little resource hungry and quirky.

The matrix foundation tracks components (clients, servers, SDKs, etc.) and their respective maturity and repos on its website.
For mobile devices, Fluffychat is the main mature alternative to Element X. And Fluffychat actually puts private use cases first afaik and looks/feels more like Signal/WhatsApp as compared to Element X.
