Depends on whether you're talking IC design (run what
ya brung) or PCB design (shop 'til you drop).
A complementary bipolar process development would aim
for things like roughly-equal Vbe@Ic (look at Class B, Class
AB outputs for why), roughly-equal beta-vs-Ic curves
across some useful range.
There are technologies like old National / Fairchild / everybody
once upon a time "Standard Linear" which had both NPN and
PNP, but made very differently (lateral PNP, vertical NPN, very
little similarity between them, PNPs really slow with poor Rc
so you see amplifier designs which use a few PNPs only where
speed doesn't matter (like DC current mirror racks) and the
whole active gain path is NPNs).
"Back in the day" RCA et al put out some pretty nice app notes
about discrete-transistor-based audio amplifiers and some of it
(as I recall) used transistors called out as matched NPN
NP
product-pairs. How well matched, how expensive or whether even
still in production, I couldn't say offhand. But maybe digging for
old RCA linear and transistor databooks on archive.org would
be helpful.
