I have both, first of all you need a big compresor. I have a 6 hp 60 gallon and even it gets a workout with a blaster. the pressure is way better but mine allways seems to get plugged up. blast for 5 mins and stop to clean out the machine, very aggravating. the siphon is a little slower but does not clog up. take your pic either will do the job.
