I have gas and diesel versions.
There is no overall advantage to direct or indirect injection. They both have plusses and minuses. For bigger engines, DI tends to be more efficient. With low power apps, both can work well.
In-direct injection is still popular in smaller engines and can be very efficient. Especially in generator sets. But, in-direct injection requires glow-plugs and does not give instant starting. Also, there is more heat-loss to the coolant when the engines get big. So, big IDI engines need bigger radiators.
Direct injection has less heat loss to the coolant, can give instant starting (no glow plugs needed). Also tends to have a lower mechanical compression ratio and handles turbo-charging better then IDI engines. Most new big diesels are now direct injected.
I wouldn't stay away from either version. All depends on what make and what it's in.
My Ford F-250 truck with a turbo 7.3 is in-direct injected and has seen a lot of heavy use and many miles with no problems. Same can be said for my Dodge with the direct-injected Cummins 5.9. I like the Dodge better, but that's because of the super-long stroke and high boost.
I also have several in-direct injected Isuzu trucks, also fine. Also two little Chevy cars with the IDI Isuzu engines.
Like I said, depends on what it's used for. If a high-power, turbocharged, bigger unit, I'd prefer direct.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
