VeeJet has a softer sort of oval pattern, doesn't have the hard impact up close but it will still have good impact 3-4 feet away. MEG has a very thin pattern, consistent across the fan. They're intended for very close use (as in 3-5 inches) and lose almost all their impact more than a foot away.
MEG tips are intended for descaling and will cut concrete. Had an idiot employee tie the handle of the surface cleaner (Millennials, he was too entitled to be bothered with holding the trigger himself), turned on the pump and left it running for about five minutes and it cut a circle about 1/8" deep.
