Given your situation my vote would be on air drivers. This is of
course assuming that you don't have to move the assembly area
around a whole lot and you already have compressed air available.
Electric drivers work well, however they do have that nasty electric
motor in them, which on good drivers will last, but eventually will
wear out quicker than air drivers.
We use all air drivers. I did buy one electric driver for some
flexibility. In my case the air drivers were here when I started and I
have continued to buy the same drivers. Air drivers will break on
occasion but in my mind are more reliable.
Having said all that, since you already have a bunch of electric
drivers, maybe it would be in your best interest to keep it consistent
for replacement parts.
OK, OK so I guess I am sitting kind of on the fence on this one and
probably haven't been much help.

PS. Dale Ernhart is a great driver....
