Full disclosure, I've never actually used Tix beyond making it build
with the rest of CPython on Windows and making sure it actually worked
on one of my Linux buildbot workers.  I have only ever seen it as a
maintenance headache :)

I have used tkinter and specifically ttk quite a bit, though, and
never felt like anything that was present in Tix was missing from ttk.

There are some things that still need to be imported from tkinter
rather than tkinter.ttk; tkinter.ttk is mostly just the themed widgets
and style manipulation stuff, whereas support functions/constants/etc.
are in tkinter.  My usual idiom is

   import tkinter as tk
   from tkinter import ttk

but it's also possible to do "from tkinter import *; from tkinter.ttk
import *" if you like the star import idiom for tkinter.

"Less available" rather than "unavailable" :).  Tix ships with Tcl/Tk
with CPython on Windows; on Linux, you'd need to install it separately
from Tcl/Tk and python/tkinter.  I honestly don't have a clue how
you'd get it on macOS or any other platform that doesn't provide it in
a system repository.

Not much has changed between 3.4 and 3.6 in tkinter-land, but I'd
still recommend the upgrade anyway.  Many nice new features in 3.5 and
3.6 :).
