If I were just rating the performance of Parallels I'd rate it a 4.0 - 4.5 if that were an option. BUT.Parallels have gotten greedy over time. The aim seems to be to force everyone onto a subscription. I dump apps that are subscription only. NO ifs or buts!Paid upgrades if you want the lifetime licence are too frequent and expensive.I'm rapidly approaching the dump Parallels position. While it's useful and has helped me when I need to run Win on my MacBook it is reaching the stage where I will drop Windows use altogether, simply because of Parallels greed.In interests of full transparency I should say that while I have used Parallels at times for some years, it was my time at a certain 'major' that got me hooked (Free licence though a messy renewal each year). Now that I've retired from there (70 + major heart attack) the pay regularly, which I've just had to do, or subscription become a greater focus
