If you want to get a sense of what the Matrix network will be like once Matrix 2.0 is fully rolled out, get yourself ElementX, and try it with an account on the matrix.org homeserver. I haven't had a chance to really stress test it yet. But from what I've experienced so far, it's a *huge* improvement on Matrix 1.0.
EDIT 2: ElementX is the Matrix 2.0 version of Element. Despite the fact that it remains significantly incomplete, and may not meet all your needs 🤦♂️
