My son-in-law went with MSG+ for this year and he hadn't complained about the quality so I asked him and he pretty much said the same thing other's have said here but maybe not to the level that others have experienced. Also, he's got Greenlight, not Spectrum internet so possibly that helps some?
I'm in the same boat as Radar, $161/month includes Spectrum Internet 500mbps down, 25mbps up. I also have free access to ESPN+ as my kids have a Disney subscription that includes it so I have all the Sabre games covered. Yes, I do have to contact Spectrum every year to "beg" for another "deal" for the following year but so far I've been successful.
