I’m brand new to Amplitude and would like some clarification on the difference of the following features. The question I’m trying to solve is: what are people’s first landing page? 

I’ve tried the following three ways:
1. under Data table chart, group by Event Name (covers all the pages I care about) under “overall” then make use of first-touch attribution after I selected “Any Active event” as the event, note that time period is set to last 30 days
2. like above, under Data table chart, group by Event Name (covers all the pages I care about) under “overall” and used Session Entries to get break down of counts of each event name
3. under Event segmentation chart, pick a page then set Historical Count = 1st ( and I will be doing the same thing for other pages to compare them against each other )

Any help/explanation are appreciated, thank you!
