I'm probably biased by the fact that the first time I got Synapse running it was the release where it'd endlessly try and fail to join a room with more than 10 people. But, every time I've looked at Matrix Chat it's been a disaster. That it tries, at all, to authenticate every personal(?home?) server as soon as you join #matrix is... Bad, from a lot of perspectives. Privacy? Just put up your own DNS and find out what new servers are joining. Security? Easy slowloris type attacks at several layers- DNS, http, etc. Performance- eagerly enumerating all federated servers before joining a channel places a hard cap on channel and overall network size. And it provides a terrible experience. The more I look, the less I like what I see. As a potential user, a software dev, and an admin it leaves me with two impressions: sloppy at best, braindead at worst.
