Just print a test object. If the motor misses steps you can hear it. Also, you can adjust the acceleration limit in Cura. I think this is the best place to do it too. In Cura you know what you are printing and can adjust based on the size of the part and if it is very tall or very wide
The 32-bit board does not really address this problem. What it mainly gives you is much more memory. In Linux CNC we control what features are used by config and hal files. But Merlin is configured at compile time. You can enable and disable features and set parameters on one of the dot.h files then you compile to binary and load in the flash ram. On an 8-bit controller you run out of flash ram if you turn on everything. The big feature many people want that just might push them over the limit of an 8-bit controller is automatic bed leveling. To use this you install a sensor on the print head that measures bed height and it probes the bed in a grid pattern. But some of the features you don't need such as supporting different types of printers or dual extruder heads or filament break sensors, changing filaments and so on. As long as you can run what you need there is not much gained by going with 32-bits.
