Cons
Con Too many variations of clients and servers (apps) and paid subscriptions to choose from for different scenarios
There's a host of downloads involved. It shouldn't be so complex to decide what software to download because of their respective services or featuresets. It should just be one client and one server with options to turn on or off different feature sets.
Con No RDP server, only client
Remmina is only a remote client (VNC, RDP). It has no server features.
