The MX Master can usually be had for $79, and has been on sale on and off this month on Amazon for $59 (was that price today, but is currently sold out).

But yeah, you've pretty much summarized the pros of both mice. The Master has more features, the Anywhere 2 is more portable.
You may also want to consider the G602. It's a wireless gaming mouse. Kinda in between the Master and Anywhere 2 in size. Has a bunch of extra buttons and features. Most notably, since it's a gaming mouse it lets you change DPI on the fly (two buttons on the upper left corner control it). This is an incredibly useful feature if you do any sort of photo or graphics editing - you can crank up or down the mouse sensitivity on demand.
