Haven’t been bitten by memory leak issues yet, but I feel for you. I had an M1 mini for nine months (lightly used) and had no problems. Switched from an i9 MBP 16” to an M1 Pro 14” a week or two ago. Have had zero problems and it’s the best computer I’ve ever had and fastest new computer I have ever used. MATLAB is 2 times fast than my Windows desktop at work, which was substantially faster than my i9 MBP. Oh and MATLAB isn’t even native yet, but running under Rosetta 2. I also have never heard the fans, even with two 4K displays attached, which ran all the time on my i9 MBP. These chips and machines are incredible.
