I also have a TP-Link Omada setup. For layer2 networking with switches and AP's it's fine. Cost effective, reasonably stable, acceptable performance and features that are regularly used are all there. The layer-3 stuff however is still early days and I can't recommend getting the secure gateway at this time. No IPv6 support. Depends strictly on an internet uplink configuration for default route to which all traffic is then NATted. Can't change that. No real security features, no packet inspection etc. The routing features really feel like an alpha version. They are working on it and have a roadmap to a more workable layer-3 solution. So maybe in the future the will be as nice as the Ubiquity solution. Cloud is not needed but possible. You can get an OC-200 controller for not much money that fills the role of single pane configuration webinterface. The software for that controller can also be downloaded for Linux on PC or ARM if you want to use your own hardware. Also the network keeps running if the controller is down.
