If I decide to go back to digital, iTunes or UV?

[PCFan]

If I decide to go back to digital as my main source for movies which I have no plans to right at this minute, should I choose iTunes or stick with UV? I have just over 300 movies in my UV collection (from buying UV codes, UV codes from my blu-rays, D2D, and Vudu sales), and 41 movies in my iTunes account. However I'm beginning to have a preference for iTunes over UV, one, because I hate the XBox One's Vudu app as the Vudu interface is clunky on it and annoying navigating around, Vudu app sometimes crashes on me on my XBox One when watching a movie within the first 2 minutes, and my movies in Vudu stutter on my XBox One.
