As should be fairly obvious from my list, I'm a fan of the darker, horror style episodes.
I don't understand the dislike for 'Encounter at Farpoint'. Sure, it has a few silly moments, but overall, its a fine first episode.
I was particularly impressed with Q, because whilst he seems a ridiculous over the top character at first, he gets progressively and genuinely more menacing as the episode goes on.
I also think that it was a good episode for launching the characters, giving most of the cast a chance to stake their claim for why they should be in the rest of the series.
'Skin of Evil' has its problems, I know. The voice acting by the villain is extremely silly, but the fact is that the episode is still a highlight, purely for what happens, and particularly for the last scene.
The last shot in particular of Data standing alone is one of my enduring moments of the whole series.
'Night Terrors' also has its problems, but there were such strong visuals and atmosphere at various points, that its an episode I can watch purely on an aesthetic level.
I don't see any problem with including these episodes as highlights, because they are the ones that get the strongest reaction from me. Now, if I'd included things like 'Justice', 'Haven', 'We'll always have Paris', 'The Loss' etc, that would be a cause for concern!
