node-red + mqtt + zigbee2mqt + tasmota is what I went with. Happy so far.
I tried everything since arduino came out and HA is light years ahead of anything else, and as someone else mentioned HA works with ESPHome and let's you use all of the platform. For example creating a data collection tool that automatically integrates with Grafana HA has for data collection. Super useful and easy to setup.
I am sure most just use the components as they are and use their own automation stuff. Like my mqtt stick that has its own automation control built in. Mixed with Google home you nearly have full control (with many limitations I know)
IMO there is simply no need for a complex interface to control a few lights and power saving tricks.
