I don't know what you mean by screen grabber. If you mean the devices that basically capture a browser window these HDMI grabbers devices are head over heels superior for PVR.
If you mean the cheap HDMI USB capture devices that people use with OBS studio the main difference is these capture directly to H264 video and AAC audio so they are effectively OTA. Their video can even be played in the NextPVR browser without any transcoding.
My current cable and Internet package gives me 1.5 GB Internet and 150 channels and 2 STB devices for around $70 US plus tax. My main reason for using NextPVR is the support comskip and NextEnd but the unlimited storage is nice. Some of the new cloud PVR's limit how long you can store recordings and you can't easily shop around for a new provider after a contract expiry because your recordings vanish.
I have used an HDMI device (HDPVR) connected to a cable STB for years. Prior to v5 I used the direct Windows support for the HDPVR and after that I used an Extra device in Linux. The biggest change came earlier this year because I was relying on the fact that there was no DRM on component video so I had to move to an HDPVR 2 (for AC3 audio) but I used one of these http streamers for general use.
The challenge of these devices it how to tune the STB. That is done with a a blaster program and NextPVR send the channel number but the user is responsible for converting that to IR for tuning. For that research LIRC. Some STB's do have http controlled tuning but that will vary.
There is a new breed of tuner that works by using an Android device instead of an STB and the tuning is done with ADB, the Android debug program. I have actually controlled the Silicondust App with ADB and feed that into NextPVR via a grabber.
