Same experience here with Android TV and lag. I have a slightly older Bravia, but the lag has always been there even though the updates for Android & firmware are always regularly updated. It was definitely not my WiFi creating the lag. I was quite happy when I got my TV about 6 months ago.
On a side note, I also have 2 Roku 4K streamers and they are a close second. The TV UI is slightly better if you are in the ecosystem. Like yourself, I have been using some of their products since the iPhone 3G.
