I looked at the B/W sprites and noticed that some of the Generation I-IV Pokemon's sprites were re-used (like Monferno's D/P sprite, Kirlia's R/S/E sprite, Magmar''s D/P sprite, Skarmory's HG/SS sprite and Scizor's Platinum sprite), with slight modifications. As for the Gen I-IV Pokemon sprites that were completely changed these are my favorites:
-Blaziken
-Sceptile
-Lucario
-Gallade
-Milotic
-Flygon
-Absol
-Salamence
-Weavile

As for the new Gen V Pokemon sprites I like:
-Doryuuzu
-Emboar
-Jaroda
-Daikenki
-Wargle
-Ononokusu
-Kirikizan
-Zoroark
-Reshiram
-Zekrom
