Roamio vs. Premiere?

I've been an enthusiastic TiVo fan since I purchased my first Series 1 more than a decade ago. Today, I own 3 Premieres and I have been sorely disappointed ever since this model was introduced. Everything from poor HD menu performance, to Netflix, to multi-room viewing via WiFi. The latter becoming far worse since last year's fall update. (I stream video better to my iPad using TiVo Stream than I do from TiVo-to-TiVo.)



At first, I read that performance would improve once TiVo activated the additional processors. I'm still waiting.



Is Roamio any better? Or is it time to move on?
