You need to remember that Zorin has ambitions to get Business adopters, hence the valid choice of choosing Evolution. From lockdown in March 2020 until I retired in August 2021, I worked from home and Evolution is the only mail client that is compatible when connecting to Exchange Servers. True you can do that in Thunderbird but the extension needed carries a monthly price tag.
Personally I prefer Evolution over Thunderbird because the latter is controlled too much by Google (You can't delete the Google search engine within Thunderbird, it is hardwired into the mail client.) I have no issue with personal email as I use e.cloud.global and Evolution picked up the settings instantly.
As for GIMP I have used it for image editing but not video editing. For me the Gold Standard video Editor is KDEnlive, often described as the Sony Vegas of the GNU/Linux. It is my video editor of choice for all my Vimeo videos.
Undeniably, LibreOffice is the Gold Standard with regard to Office Suites as it is the only office suite that has more language support that even Microsoft cannot claim. However, Libre Office documents, even when saved as MS Word, they don't display correctly on Work Machines. For me, the only office suite truly compatible with MS is SoftMaker Office. Fortunately for me I had just paid for a 5 machine licence of SoftMaker Office in the November prior to the Covid outbreak for just under £25. It is available for all platforms. It's ribbon is more practical than that of MS. My workflow for Documents and Presentations was much more fluid and quicker than MS equivalents and when files were saved as MS ones they displayed correctly in MS Office at work. The only issues I had was with font spacing (% instead of Points) and no image compression, both easily worked around by creating font spacing in LibreOffice Writer then opening in SoftMaker to see what the percentage was, and simply copying document images into Writer, using the compression tool, then pasting back into TextMaker. The Windows version of TextMaker even has MathType integrated into it. Sadly not possible in Linux as Linux uses Unicode not ASCII.
In respect of browsers, I still use Firefox but again Google has too much invested in it. GNU/Linux is about freedom from mainstream ideas, adding mainstream apps to GNU/Linux erodes those freedoms. One of the biggest issues is the use of Java. Stallman advises we should complain about websites that use Java. I use image.bb for uploading images on boards/forums that don't allow images to be posted as image.bb doesn't write Java code all over their machine. Chromium is a better alternative for privacy, and for absolute privacy, Icecat. In terms of Firefox Zorin should be implementing Firefox ESR (Extended Service Release) especially for Education as ESR is the only version that can be locked down. Antix and Devuan both come with Firefox ESR by default.
Clawsmail is another good email client.
Forgot to mention that Gmail is the problem and not Evolution. Similarly KMail in KDE needs a code from GMail before it will work. But KMail is poor because of Akonodi which keeps making it crash, not stable at all. So who knows what 'spyware' GMail might be adding? I have a GMail account but don't use it much these days. I prefer @e.email and @protonmail.com (I signed up for parallel @proton.me but don't use it. My daily email is the e.foundation one.
