Since others have posted their lists, I might as well post my own:
	
female:
	1) Orikasa Ai (she merits a -sama, IMHO ^_^)
	2) Ogata Megumi
	3) Hayashibara Megumi
	4) Takano Urara
	5) Kawakami Tomoko/Takayama Minami	
	6) Kotono Mitsuishi
	7) Suzukaze Mayo (Takarazuka actress, I know...)
	8) Tanaka Mayumi/Hidaka Noriko
	9) Sakamoto Chika
     	10) Kobayashi Yuko/Sakamoto Maaya (more of singing than anything else)
	
	I heard a sample of a Ruroken radio? cassette? drama where Ogata Megumi
plays Kenshin instead of Suzukaze Mayo.  Ogata's "male" voice is fuller and
deeper in comparison to Suzukaze, but it is Suzukaze who does a better (and
funnier) "Oro!".  I take the "Oro!" into consideration since it's my most
favorite Kenshin expression. :P 	
	
male:
	1) Seki Toshihiko
	2) Seki Tomokazu
	3) Sasaki Nozomu
	4) Hiyama Nobuyuki	
	5) Ishida Akira 
	6) Midorikawa Hikaru
	7) Furuya Tohru
	8) Shiozawa Kaneto
	9) Yamaguchi Kappei
	10) Kikuchi Masami	

	The two Sekis are most likely to swap places soon, but there isn't much
contest between them as of now. ^_^
