I was lucky enough to get a 4 tuner OTA TiVO Edge last year when my remanufactured Bolt died under warranty. My wife loves it but the tuner sensitivity is crap. I also have a 4 tuner new Tablo.
Tablo picks up over 100 OTA channels. Tivo about 30 on the same antenna.
The TiVO DVR is still the best but I doubt they will be around much longer since they are not selling a OTA box anymore and cable card's are being discontinued everywhere.
Our DirecTV Stream subscription gets the most use with a Ospry/Gemini box I bought before DirecTV quit selling them.
I am satisfied with the new Tablo. It can be finicky at times requireing restarts but it seems to be improving with the latest software.
