Ugh...I just noticed, there's no way that's Noriyuki Iwadare is doing the music, that's clearly Level-5 music.
It's a good thing that Level-5 games usually have amazing music.
Noriyuki Iwadare's music is way better than Level-5's music. Never in any Professor Layton game I have ever played have I ever felt the same when that Cornered 2004 Variation played when Gumshoe yelled OBJECTION! in Trials and Tribulations. Never in a Layton game have I ever found myself humming a track from it, save the title theme. The music is one of the best parts of Ace Attorney..
Hopefully Level-5 will remix some Ace attorney tracks..

This is the single most epic thing in the universe. Case closed.
But aside from that, I'd say you're wrong. Phoenix Wright and Layton may share gameplay elements, but the style and feel of the two series is very, very different. AA is tense, exciting and dramatic, whereas Layton is more laid back, mysterious and of course puzzling. The compositions for both games reflect this. It's like saying Canon in D is an inferior song to the 1812 Overture because the latter is more fast paced and exciting.
Incidentally, I whistle the Layton puzzle themes all the time.
