Ubuntu is good to start with. Also, you should consider the Elementary distro, they have a focus on stealing Mac users https://elementary.io/ could be right up your alley. As long as you use Ubuntu or Elementary - any of the more ui friendly & compatibility focused distros you'll avoid a lot of the common problems that frustrate new users. After you're comfortable with that... wander over to https://www.reddit.com/r/unixporn/ and take your desktop up another level. I use both Linux and Mac and never find myself wanting a particular app from Mac that I don't have available to me on Linux. I find myself needing things like xcode for builds, but certainly not wanting it. If you're a music producer Logic Pro is the one app you'll miss.
