FFmpeg on the command line on Windows has been fine for me every time I use it, using the Zeranoe builds. They seem to come with the right codecs and everything.
Those are the ones I also use and it hasn't been flawless for me, BUT I tend to do a TON of video for professional production (Happens only a few times a year). I get hiccups that I don't know everyone would really notice or care about, but is HUGE for my purposes.
