If you stream more than you watch OTA television the Stream+ might be for you. If you watch more OTA television than stream, you will probably be disappointed and are better off sticking with the DVR+. The Internet guide for the DVR+ isn't necessarily coming to an end, either. CM is working on keeping it going, but there is nothing definite yet, so it could go either way. You can always get your "couple of days in advance" by supplementing the PSIP guide with an online guide. Bottom line: At the current time, there is no perfect DVR, and there is no perfect guide solution. All you can do is weigh the available options and live with your choices.
I actually disagree with this. The Stream+ is nearly equal to the DVR+ in terms of OTA recording / viewing if you are just interested in time shifting, but not very good if you stream a lot. It no longer has the Hulu app, and has never had Prime or Netflix. They have never gotten certification as an Android TV box, so I think as a streamer, it's far less capable than a Roku or Fire TV stick.
At the time I abandoned it, the Stream+ did not have a 14 day channel guide IF your local market had more than about 100 OTA channels (or if you added in Pluto TV channels that brought the total ABLE TO BE RECEIVED up over 100). Note this limitation had to do with the number of channels available, not the number you have shown in the guide. My understanding is that this has been fixed and you get the full 14 day guide now.
It also did not do "chase play", where you start recording a show at 8 PM, then start watching that recording in progress at 8:15, intending to skip commercials until you get back to "live" status. I don't know if that limitation has been fixed. Since memory issues are the reason for the restrictions, I suspect chase play is still missing.
Those aside, it works very well as an OTA DVR. But if you watch Netflix, Prime or Hulu, then you will need another streaming device like a Roku or Fire TV. So, that's really on parity with the DVR+, where CMTV never did get the ability to stream those either.
