I think it is pretty obvious that pneumatics are the way to go (just in case it needed to be said :) )

When I was into a bit of blacksmithing, I used pneumatics to "stoke" the pyro (fire) ;-) The flywheel blower or the home made bellows.

well i like pneumatics but i just can never think of a good cheap way to make a trigger to let the air out....(dont want to go to rona to get a valve).... i like the fact that pneumatics wont get the cops at your house cause there quieter but im also afraid of the air tank (a 2L bottle or w/e) blowing....then again a combustion has a chance to blow up completely and kill you....but w/e i like pneumatical

combustion FTW -Pyromaniac friendly -No pumps or compressors needed -Pneumatics have a harder to minimize concept (You can make mini spudguns, but mini pneumatics...?)

A good trade - a 10p biro, a (non-medically) used syringe, a blob of glue and a few minutes of my time to entertain both my sons for a day.

Pneumatic.

It's down to requirements, aims, materials and the law.

Pneumatics will launch things more gently, explosives give a sharper thrust.

Pneumatics can be very controllable, explosives are all-or-nothing.

Pneumatics can be made with lower-tolerance (and less flammable) materials.

Pneumatics can be more vulnerable to leaks.

In the long-term, pneumatics are cheaper (it just needs physical effort to reload, not the expense of more fuel), and can be a lot cheaper to make several (such as with group work).

Pneumatics are less likely to contravene local weapon-control laws.
