Well, that plus the fact that they are much smaller and lighter, and don't have any of the funny interfaces that the Mercedes fuel systems have. A VE pump only has fuel and one small electrical wire going to it (or technically two on the '85-'86 and a few rare '84 pumps in West Coast cars). A Mercedes pump means fuel, motor oil, and the vacuum system all have to interact in one component and the results of that can be messy. When those vacuum shutoff actuators fail, which they do all the time, they can spread black diesel engine oil all throughout the car's vacuum system... in the doors, in the dash, etc. I have worked on W123 diesels that have big black stains in the carpeting in the driver's footwell from where oil got into the ignition switch, damaged it, and ran out all over the inside of the dash and down into the footwell. You won't see that issue on a VE pump motor...
