If you like to analyze chess positions, and you give more than a few seconds of time, then Houdini is a must have.

For tactical positions, it simply is the best.

There are some experiments in the Rybka forum showing Houdini's prowess.

I only wish there were a Linux version.
I have not tried Houdini 6, but Houdini 5 works well for me in Ubuntu (Mint) via Wine.
My Linux machines are all NUMA at home. I read that there were problems configuring Houdini for NUMA on Linux.

Besides, I want no taste of Windows on my Linux systems. It's time for me to make a clean break. All my new systems will be some form of Linux (Last one was Ubuntu, the one I just bought will be Centos).

I have thought about Mint. I might try some others.

Stockfish is drawing the weaker engines to much. It looks like there will be a new TCEC Champion this year.

That's quite possibly true. I doubt that Stockfish will get the needed full points in the last 4 matches.

But its performance was far from disappointing in my opinion. Let's see if it stays undefeated.

And although I like SF the most, a Komodo - Houdini Superfinal will be interesting nevertheless.

Perhaps you play even faster than 40 moves in 4 minutes? Or it could also be a configuration issue
No Configuration issues.
Yes, much faster, 4'+2" or 12'+1" Matches, that is, Blitz or Rapid.

I watched stockfish 8 vs stockfish 8 on my S7 edge handphone very often and noticed that Stockfish drew a lot of games with threefold repetition. May be a little bit randomness ( let say within 0.05 evaluation) might help to improve stockfish.

Indeed - SF missed out this time.
Komodo v Houdini in the SuperFinal.

Also, a very nice showing by Fire 6.2 in Stage 2, the only other engine to finish above 50% in Stage 2 besides the Big 3.

So I was right to hope for a Houdini / Komodo final this time. Now I would bet than Houdini is the slighty favorite here and says he will win with 52%.
I think contempt helped Komodo a lot but might be a little less strong in head to head, even if Houdini is not update. But I might be wrong if the next Komodo has won some more elo.

They announced a Houdini update in chat.
