First Basic Eurorack Planning Stage

I am planning a first basic Rack to get into the usage of a eurorack step by step. I want to send voltage from a microbrute and use this first setting to get into patchings etc. So the first modules should not be too complicated, but they should be of good quality to work with them as a basic later on as well, when I add other modules step by step. Do these modules fit their purpose or should I replace any of them by a module from another Company? Fell free to give suggestions.
