I like many of the new cries.
I wish they would revamp the 1st, 2nd (and, perhaps 3rd) gens's Pokemon cries. It's just weird to listen to some nice, realistic cries alongside weird, computer noises.
I guess my favorites (for now) would be:
Muurando'sShibirudon'sShandera'sZeburaika'sWarubiru'sBaffuron'sUrugamosu's; kind of reminds me of foliage catching on fire
Kobaruon's; reminds me of a precious stone, or something spacial, like a UFO
But my top-top faves from this gen are:
Warubiaru's; it reminds me of a chainsaw
Birijion'sBorutorosu's; it's wind, followed by thunder
Reshiram's; something heavenly
Meroetta's
