My general advice would be to try the Takeda Gyuto first. Some people really go for them and then add others. Personally I think it's way more fun to try different makers. You learn more about knives by doing this and it's fun to have an eclectic collection instead of an all matched set. At least that's the way I feel about it.
If you want to try a really boss nakiri that's hand made the Shigefusa is a fantastic knife http://www.chefknivestogo.com/shkuna18.html
