Yep, I agree with the above. But even Tumbleweed sometimes has stability issues that need to be dealt with from time to time. What you're describing about ZorinOS or Ubuntu are actually very useful design decisions. It's simply not what you need, and that's all right.
Since you were willing to make a second purchase of Pro, please consider using that money, or some of it, for other projects instead. As you mentioned MX Linux, I'd suggest that.
