8inch Maksutov is better than 10inch parabolic reflector if you observe planet,
10inch parabolic reflector is better than 8inch Maksutov if you observe nebula in the deep sky, without any chromatic aberration,
ED127 is better than reflector, Maksutov, if you observe objects on the land besides sky observe.

Welcome Heiko!
Gilman gave you good advice.
If you want to view planets, a long focal length is good, meaning the 200mm Mak would be a good choice. But, the Mak will have a narrow field of view and would not be so good for large deep-space objects like the Orion Nebula.
The 10-inch reflector will be good for deep-space and OK for planets if you use a barlow lens, basically it will do everything, but it is very large to carry around.
The ED127 will be very good for deep space. Not sure about planets at high magnification, you may get false colour (chromatic aberration) around the edges of bright planets. I will report when mine arrives
The 4" Mak? Maybe a bit small, however a very lightweight user-friendly scope for a beginner. Very similar to the Meade ETX90 I guess?
