As someone who is madly in love with this show, I only have a few episodes in the whole show I don't like. 
In Season Three the only one I think of as "not very VOY-like" is THE CHUTE. That one is not to my taste at all. And this in spite of the fact that Tommyboy plays a major role on that one. That episode is too dark for me and would do much better on dark shows like DS9.
I love all the others that have been mentioned before as pretty much disliked by the others - SACRED GROUND being a big fav of mine. It is simply a beautiful story in my book - Janeway shines in that one (doesn't she always?
)
My fav episode of that season is BLOOD FEVER - that one is a gem. It's the third best episode of the entire franchise in my book.
Also, Season 3 features one of the most relaxing holodeck environments they have ever created in any Star Trek shows - and in contrast to popular opinion, I find that that one is a pretty unifying element of this season: a lot of the stories will take place there. Most of the times, we only see it for a minute or two but it's surely a "trademark" of this season.
In addition, this season will start the borg storyline - and I think they are the second best villains of VOY/ST. A good borg story is always a great delight to watch, isn't it?
Btw, I do agree with the others that FAVORITE SON is a bit of a letdown. But then, like you said yourself, Harry is not the most interesting character on VOY.
