My favorite English actors are currently:
Travis Willingham
Wendy Powell (Mostly because she plays Envy and we saw her in person... but she's still great
)
Vic Mignogna (Not only because he has an awesome voice and plays many of my favorite characters, but because he's such an awesome person, too... A Christian, a singer, hilarious, really nice... what more could you want? XD And he was really nice at the convention, too... Got a chance to sorta talk to him a couple times
)
Yuri Lowenthal (I admit to liking his voice as Sasuke... and I have an ongoing joke with myself about how I keep not realizing how many of my favorite characters he actually plays! It took me ages to realize that he was also the Prince of Persia... and then Suzaku was a new discovery... And then came his Bleach role... And then I realized he did the English adaption of Luke and Asche... and just now, I found out that he does Cecil from FF4. So... even though he's not all that great of an actor for most of the charries I've seen him do, and tends to sound sort of unenthusiastic, I really do like his voice)
Yui Makino (Sakura in Tsubasa Reservoir Chronicle... one of my favorite things about her is that she also sings the song from it, which makes it SO much more interesting)
Japanese-wise-
Daisuke Namikawa (Plays several of my favorite characters, and is just awesome XD )
Mamoru Miyano (Again, several of my favorite characters, and can anyone say 'emotional range'?!)
Chihiro Suzuki (Mostly for the sake of Luke and Asche from Tales of the Abyss. He had such a unique way of showing emotion, and showed the emotions of both characters so clearly. I had to love his voice, of course
)
