What's the difference in the chronological order and release date order of Haruhi Suzumiya's?

I mean isn't the release date order easy to understand since it's created that way. But people keep saying chronological is good. So I'm confuse what's the difference. Isn't anime created according to manga/LN (idk which this series has). If that's the case then isn't release date order easy to understand?

And if I watch chronological order then aren't I watching episodes in middle of another arc. So isn't that gonna hard to understand?

I never watch any anime in chronological since their release date order are better but why people keep saying this one's chronological order is good?

So if anyone kindly explain what's the difference between this two I could finally watch the anime.
