It'll take me a while to decide between the two, so for nicest notes, I'm going with both the 1937 $100 and 1954 $5.
On the note of 1954s, the colours started off quite vibrant with the Devils Face notes, but then as they were about to be replaced, the colours were quite faded in comparison. The $1, $2 and $5 notes especially, but all of them to some degree. This fading over time is in my opinion a terrible change made by the Bank.
For worst notes, it's either almost the entire Multicoloured series as a whole, or the faded 1954 notes. The Birds notes were OK, I like the Journey notes, the 1937s mostly weren't my preference, and I haven't seen enough of the 1935s in person to get a good appreciation for them. I'm not into Chartered notes, so I can't speak there either. I've got a couple Dominion notes, but nothing to speak of.
