That's a matter of perspective, really. The reality is that Windows is not Linux and Linux is not Windows, so it's natural to meet some resistance as old habits die hard.
I've been using Linux daily for a few years now, and I struggle to get something done in Windows that'd take me seconds otherwise in Linux. And not because "Windows is complicated compared to Linux" but because I'm not used to it anymore.
I had the exact same issue when I first used MacOS, and then again with Linux, after decades of using Windows.
Now, a lot of work has been done in recent years to make the desktop experience on Linux much better, but there is still plenty of room for improvement, such as in this particular example. One reason for this is precisely because of what makes Linux great: modularity. The same technology can be implemented in different ways which makes it highly flexible, which is why it may look and behave differently in Zorin OS Lite than it does in Zorin OS Core or Linux Mint.
With all that said, you should definitely use whatever works best for you. Personally, I don't use the main application menu anymore, ever since Windows Vista, and later Windows 7, made the search functionality so good that it basically made the menus a thing of the past. Just hit Super/Windows key, type what you want, and Enter.
