Windows 10 - so slow to start up. I don't like the UI design.
Ubuntu - fast, but somehow after upgrading to 18.04 my number key pad doesn't work without running a command, so annoying. hardware support is still an issue but there is always solution if you know how to use Linux
OSX - beautiful UI, very stable and fast experience. I am not a fan of Apple. My Macbook Pro is the only Apple product I have and I can say it is worthy price.
Occasionally, I turn to VirtualBox. Either I'm doing something completely Linux-related (mount points, loopback, linux-headers) or not at all.
I'm also trying out options like ImDisk but really wish Windows would allow -o loop; Have used Docker with Hyper-V; Not used WSL yet. Plan to do so once Microsoft add Linux FS mounting support.
As far as Ubuntu goes, no - not really a fan; I just seem to be liking Fedora more these days.
- I had to fix the time on windows to use UTC instead of localtime - I had a bit of trouble with ext2fs on windows, it tried a few times to format my disk.
Apart from that, I'm not noticing any serious problem
I use to user opensuse on my workstation, but had an issue and just switched to 18.10.
I use a win10 Lenovo desktop and a laptop running Zorin Lite, which is basically Ubuntu 16.04 + xfce.
zorin lite is FAST, booting win10 feels like driving an old minivan.
Pretty much just use the win desktop for Adobe suite, Linux for everything else!
I don't like using git on windows but that's purely emotional.
