Explaining My Experience:

Komodo:
It is very strong engine. It's positional understanding is amazing. Where other sees draw, it still sees something to manipulate. Even in quiet position. It's hash system help to you preserve analysis for later.
For Complex ending and opening theory ,komodo is preferable. For big project with more than 8 cores, Komodo is highly recommended.

Houdini:
Once upon a time , Houdini was only reliable engine for it's deep accuracy and rational evaluation system. When other engines were flawed, it was 90% tactically accurate. For early middle games, Houdini is preferable. Because more you go on against it, it sharpens the position both tactically and positionally. You are left with limited options with strange dilemma.

Stockfish:

 It is an open source and free engine. It is tactically monster. From very early of the game, it aims at mate attempt. Once you get weak in the king side, no one can save you. It is very aggresive and dynamic  in playing style.  Sometimes it sees move, other can't see. It is small in size but very fast and one of the Strongest.

Komodo excels in imbalanced positions.

Next  want to show evaluational difference between those.

Would any chess engine expert recommend their parameters setting? Like, how to make one engine prefer material sacrifice, one engine prefer closed position and one prefer open position...

Go to engine options. Change 'Contempt" and "Selectivity".

yes, Stockfish is free.

One can learn more  by using manuals.

I'll wait until Google's Deep Mind Alpha Zero is available.

Leela Chess Zero, Google It. It's a killer engine

I don't cheat, it's freely available for post-game analysis, which is what I use it for.
