I’ve always felt they weren’t really worth it for performance per dollar spent. For C++ work I just use a non-Mac workstation. For lighter workloads the Mac Mini is very capable already.
The Studio (Stud IO™) is the new Mac Pro - it's not "worth it" unless you need the most performance period - or you have money to spare.
Or you really, really need to drive eight displays from a single machine.
For "home user" stuff a Mac mini or MacBook is going to do everything you ever need (in fact, they have the problem where the M1 systems are still perfectly capable, six years later).
