I have to many Engines to list but it's like they say it really depends on what you are looking for, Cheap, Expensive, Detail, Extreme Detail, Pulling power, capability (Gang-ablity), continues non stop running capability, price range, Ect. It really depends on what Engine model you want, for instance, (in my own personal experience)
F7
Life-Like Will out pull any kato and the detail is pretty good although a little out of scale from actuality but while running it is so perfect.
Kato is top dog in detail and prototypical scale size & It runs well in slow momentum speed where the Lifelike Lacks due to the fact that Life-Like does not have Dual brass flywheels.
PA's
Kato will out perform in just about any category except Pull-ablity
Con-Cor Will beat in pulling strength.
There are not to many models to compare to so it really depends on what Era you model like Modern
Kato
C44-9W
AC4400
SD70/80/90M's
Atlas
Sd50/60/60M's
Life-like
They Have not came out with a To modern Engines so it's hard to compare them to this category.
Let me know what Era, Motive Model's, Year's and whatever and I will give you my personal experience.
