Which would you prefer?

Still need knight tanks (Pal and SK) to tank trash mobs on the way to the bosses if you want to kill fast. Warrior aggro is still garbo for quick kills.

Warriors will be tanking the big bads almost always, but the Knights will still be important. They'll be tanking a lot more mobs than people would have you believe in raids. Anyone who says otherwise hasn't actually raided Velious.

Also knight tanks can tank almost every single Kunark boss just fine minus VS and certain mobs in VP. Pallies can probably tank VS in theory with Sanctification disc. once Velious comes out fine too. Kunark bosses are still important even in Velious.

*EDIT*

It's all about how you want to play. Honestly, if you want to raid -- make both.... and a cleric.. and a wizard.. and a rogue. Raiding on P99 is all about multiple characters.

If you want to just chill and group -- play what you want.
