For me, they're tied.

And not in a good way. =\
Both albums had really good singles... and then both albums had ****** album tracks.

But why ask this at an Ayu forum? XD

damn I like both albums as they're good in their own right but I pick (miss)understood

(miss)understood... never heard Ultra Blue though so I'm not sure that's fair lol

HAH! Silly question lol, everyone knows ULTRA BLUE reigns supreme... And that's not just my fanboyism speaking, seriously, ULTRA BLUE is way more superior.

(miss)understood. The only reason I didn't pick ULTRA BLUE is that there are two songs on the album I didn't like versus the one I didn't like on (m)u.

(miss) understood

ULTRA BLUE is better than Ayu's (M)U i think..

This time Ayu's (M)U is a bit disappoint for me, but Hikki's ULTRA BLUE has caught my attention..

(m)u wins I only skipped criminal that's all

But ULTRA BLUE on the other hand...I skipped almost 3 tracks or more

(miss)understood, because ULTRA BLUE is kinda boring album imo. I love (miss)understood so much. <3

(miss)understood

(m)u is my absolute favorite album!

Hard one!
I prefer (m)u, but ULTRA BLUE is really underrated

(miss)understood hands down.

(miss)understood
'Cause I'm not big fan of ULTRA BLUE and Utada either.

My favorite Hikki album versus one of my least favorite Ayu albums...

so Hikki wins :)

(miss)understood

It's my fav Ayu album.
..and I'm not a huge Utada fan.

I love half the songs on Ultra Blue: Dareka no Negai ga Kanou Kara, COLORS, Kairo, Be My Last and Passon. I adore these songs but the rest on the album kinda blend into one for me.

Whereas on (miss)understood I love all the tracks except Beautiful Day. (m)u wins!!

(miss)understood

it's my favorite album!

(miss)understood = my favourite Ayu album!
