Better transistors for class-A bias?

[philipsmarantz]

The Tangent Pimeta2 I mentioned in another thread uses several common TO-92 transistors for bias op-amps ( into Class A).

Tangent suggests:
Q1, small-signal PNP ( 2N3906 and the 2N5087 are known to work, as should the PN2907)

Q2, Q3L, Q3R, small-signal NPN: (possible: 2N3904, 2N5088, and PN2222.)

Any improvement possible by, say, upgrading these to Japanese, Zetex or other models by "better" manufs?
