The only role I will ever use a 12AU7 in, is as a follower. In such use any to spec 12AU7 should be fine. 100% local feedback doesn't hurt in achieving that.
For gain duties? Unless you have serious heater current limits in the PSU of pre-amp or power amp, you should consider a 12BX7, at least. Other possibilities require a rewire as well. All would give far lower distortion and lower output impedance. ECC99, and 6CG7, 6FQ7 ....
