Engines style of play: positional/tactical

[Marc Benford]

Hello.

I’ve heard that each engine has its own style of play. Some are more positional and strategic, while others are more sharp and tactical.

And so my question is: could you roughly sort the following engines from the most sharp and tactical to the most positional and strategic?:

- Critter 1.6a
- Deep Fritz 14
- Gull 3
- Hiarcs 14
- Houdini 4
- Komodo 7a
- Rybka 4
- Stockfish 5

And does the style of an engine depend on the time it takes to get to a high depth? I was thinking that maybe, for engines of roughly the same strength, engines that quickly get to a very high depth are more sharp and tactical, while engines that do not quickly get to a high depth have a richer and more complex evaluation function and therefore they are maybe more positional and strategic.

Thanks in advance for your answers.
