What are the advantages of different injector air bleed sockets?
I kind of ended up with a set of third gen primaries paired up with second gen tops, and also my old first gen sockets as well. Both sets are in decent shape and it seems they both fit, so now I'm thinking which ones I should use with the new motor, which has second gen N/A center iron with bigger ports. Do the third gen air bleeds perform better or something? Why did Mazda re-design? Was it because of the turbo?

Well, that's what I was thinking, but I asked in case there's any advantage to using the later versions of the air bleeds. Maybe they're better at "atomizing" the fuel or some such.

the FD/cosmo engines have a different port shape/angle compared to the FC/gsl-se engines, so i would not mix those.
of the gsl-se/FC motors you'd think the s5 ones were better, but for what? the -SE ones are setup to work with larger injectors, so i dunno

Keep the air bleeds/oil injectors that came with the engine. The S5 and FDs were computer controlled, all earlier ones are mechanically controlled by throttle position.

In regards to the oil injectors. The 3rd can run the oil mix as lean as 1:500/800, where we premix at a ratio of 1:128. The 3rd gens also have a high engine failure rate under 100k, many in the 60-80k range. Much of this is due to the extra heat the twin turbos produce.
