Many years ago I purchased a Spanish brand Ibertern 0-4-0, it was fairly well detailed for its day, and once run in was acceptable - for the time.
Recently some of the smaller Japanese specialty brands like Worldcraft have made 0-4-0's. They run like clockwork, but are expensive! I hope posting commercial links is okay....

I have a Microace 2-4-0. It runs well.
I've seen 2mm Society members in the UK scratch build 0-4-0's that run well.
All of the models described above have a metal body and chassis.
I've had a few Bachman 0-4-0's - the Docksider and the tender version. These were designed in a different time, there was no 3D CAD, they had plastic bodies, chassis, and came with a very average motor. BUT if you replace the motor, they run reasonably well. The Bachman 0-4-0 chassis and Ibertern 0-4-0 chassis is popular with 009 modellers in the UK.
So the moral of the story for a any new massed produced 0-4-0 model is the designer must consider a cast metal body. And engineer the mechanism with a decent motor.
