That depends on exactly what you need your system to do for you, and in what way, and what kinds of customizability you require, if any.

You'd need to create for yourself as complete a list of required features and functions as you can imagine. If there are features that are not required but are desirable, make them a separate sublist.

Then look at controllers that have all the required features, and make a list of those. If any of them also have desirable features, then those would go to the top of the list.

Then you can look around for people with problems with any of these controllers, and how they were resolved by the manufacturers, assuming there was any support available, and any attempts were made and described. You can also directly communicate with those manufacturers you are considering, to see how well they do in this--if they don't perform acceptably, take them off your list.

After that, then you can sort the list by whatever other criteria you prefer, such as cost, size, time for availability and/or shipping, etc.

It's very possible that you won't find a controller that meets all your criteria, and if that's the case you'd need to decide what you can compromise on. If there are no requirements you can give up or alter, you'd be at the point of picking a controller platform you have the ability to modify to meet them, and go with whatever is available in those that meets all your other requirements, etc.


My personal opinion is that there are NO controllers out there with sufficient user-friendliness for a basic DIYer that are also sufficiently customizable, that also have sufficient support.

The closest I have found (based mostly on member threads here) is the Phaserunner series because Grin Tech created their own setup software for it, and they are often (but apparently not always) available to help with issues setting one up when the automated routines and info in the manuals don't complete the job. But it's a relatively low-power controller, probably not suitable for your usage given the 100A requirement you have, not knowing any of your other requirements.

After that, it gets beyond basic DIYer and into advanced stuff requiring either altering software or hardware or both to customize sufficiently for some purposes. Easiest to do this with are open-source efforts like the many VESC projects, or the Lebowski brain (for which you must provide a powerstage, but which means you can make it as powerful as you want).
