I used my pneumatic quite often. It lacked the oomph to break bolts free but you could just use the body to break the seizure and then use the action to run the fastener out. It has the 90 on it to get into tighter spaces like header bolts and timing cover bolts.
i can't remember the last time i used my air ratchet. it seems like the bolts i would use it on are so short it's not worth firing up the compressor, or there's nothing in the way and my M12 1/4" hex driver works well.
