All those others worked okay, but AllVideo Share loads videos the fastest, integrates better with modules, and is WAY better for mobile display than any others. I was getting really tired of testing different extensions and thinking "I wonder if it's gonna play properly on THIS device, or in this context"... with AllVideo Share, my videos work everywhere, every time. Hooray!!
Also, if you want a commercial license to get rid of the 'powered by' text, it's a better deal than any other video player as far as I can tell. $49 one-time flat fee, as opposed to most others which charge $5/month or more.
