what is the best settings for ESGST

The ones you need.

My settings include Grid View, Endless Scrolling, Filters (I like "Projected Chance per Point"), Bookmarks and they are awesome (probably other things I do not remember right now).

That said, Steamgifts has been very slow for me in the last few months, probably related to my use of ESGST, so take my advice with a pillar of salt.

Cheers!

I've used min-max settings for ESGST (or similar add-ons/scripts) in the past. I've lost all of them, so now I just use the default settings offered by the wizard the first time I run ESGT. Infinite scrolling is probably the most annoying thing I disable every time.
