Thodoris:

which of two is better for live situations?

Probably the PF, but it depends on what you are trying to do.

Thodoris:

Can Pitchfactor change its presets and settings only with a foot midi controller?

If you have a suitable controller – it will need to send both Program Change and CC

Thodoris:

Can i place it in a rack drawer and after the extended programming just plug a midi cable and leave it there?

In most cases.

Thodoris:

Will Pitchfactor be more quick than Eclipse?

In most cases.
