I used the air method till my compressor broke, a bit fiddly and there is a definite knack to it. The benefit of a compressor is you can take grips on and off without wasting the grip however I found corded and MC grips didn't come off easily with air and had a tendency to blow.
That's why they recommend the use of a tube around the outside of the grip. By the time you've got the compressor out and running (especially if it has a reservoir), faffed around with the guard tube and blown up a couple of expensive grips, you could have it all done and dusted with tape/solvent.
