4th Gen What was your favorite Legendary Theme?

Although I have both games now, HeartGold got me back into Pokemon since I took a break after Emerald. I prefer HeartGold over SoulSilver because Ho-Oh's theme is possibly the best Legendary theme in any Pokemon game in my opinion. 4th Generation's soundtracks were certainly..... God-like compared to other games.
So, which do you like better? HeartGold's Ho-Oh theme or SoulSilver's Lugia theme?
EDIT: To add a little more to this thread, I'll include all of the 4th Gen Legendary themes.

Out of all the legendary theme songs, I'd have to say my favourite would be the Lake Trio's. The music was so majestic but upbeat at the same time, and really put the suspense in battling Azelf, Uxie and Mesprit.

I've always liked the Giratina theme from Platinum, extremely frantic and trippy, I think it matches the Distortion World and the events with Cyrus really well. The Lake Trio song was really good too, but I got a bit sick of it after spending 2+ hours trying to catch Azelf my first time around.
