Which plane is most interesting to be trained on: DR400 or DA40 ?

From here

The full fuel payload is great (more than a TB20 actually, which is 260kg, and has the same empty weight of 900kg) because the fuel tank is small. OTOH it doesn’t burn much of the stuff to start with.

The DR401 (155 HP) can take 4 POB and a reasonable amount of fuel. I expect the same goes for a modern DA40 with 155 HP.

Unfortunately not. You need a DA40 NG to get a better payload. The DA40D 155 HP is still limited to 1150kg MTOW.
The DR401 wins at payload: 460kg useful load or 385kg useful load with 5hr of fuel on board.

I also like the da40ng a lot

I did my IR with a new NG (waas and gfc700). Yes. That’s a bird. and the AE300 are a lot more calm and feel “safer” than the centurions.

Even though the performance is not such a big issue. Both engines do quite well (2.0s and AE300). Just speed is a winner for the da40. It does easily cruise 145ktas at almost all levels

If I could choose, the ng airframe and the 2.0s would be interesting. But no such luck…1150mtow for centurions :-(

And you can go to croatia in one go while the DA40 would struggle (or might even not manage) to do it with 1 stop! Good thing is fuel is generally guaranteed available at any decent sized airport (for diversions etc)
