Parallels.  AtLA and tLoK.  Looooooove this.  Kataang and Korrasami

Honestly Kataang and Korrasami (even though I haven't finished LoK yet) just give me a nice, happy feeling inside that makes me feel at peace.

Powerful as the avatar......oh wait, thats right.

Katara & Aang I feel like the ending would've more genuinely shown their feelings without the kiss, but maybe thats just me.
