Sling vs YouTube TV comes down to price versus completeness: Sling starts at $40/mo with a leaner channel list, while YouTube TV is $72.99/mo with locals, unlimited DVR, and more streams. YouTube TV offers more channels (100+ vs 30-50 depending on plan) and includes local channels in most markets, while Sling TV costs significantly less ($40-55/month vs $72.99/month) with customizable channel packages but lacks local channels in many areas and charges extra for unlimited DVR.
