I don't care if people laugh. Never have. I actually prefer GIMP to Photoshop. (I have both.) Thought I'm still annoyed at GIMP for removing the "save as" feature and making "export" the same option.
As for Acrobat, there is no alternative. I do much of my work - performance evaluations, my evaluations, time off requests, overtime requests, purchase requests - in Adobe Experience Manager. Not only do I need to be on Windows (7, 8, 10) but I need to have IE. I used to hack this stuff together using WINE (http://perfectreign.com/stuff/2009/20090614_wine_excel_2007.jpg) but gave up around 2011, with it becoming increasingly impossible.
That said - we have several hundred servers running RHEL, and several dozen of our web servers run on various zLinux servers. I believe many of our Cisco servers are Linux also (though I'm not sure).
Keep in mind, I used Linux since the late '90s - http://www.perfectreign.com/2014/08/15-years-of-linux/ - so am somewhat proficient. I still use BASH on my Windows OSX machine - https://twitter.com/PerfectReign/status/724771094566072320
