I'm probably sounding like a broken record by this time, but none of these are Equal-i-zer hitches; it would be nice if Escape properly labelled them as "weight distributing hitches".
The Fastway E2
does use a similar style of bar-to-frame brackets to that used by Equal-i-zer, unlike the Pro Series
. Those brackets add friction for sway control... and likely noise, and wear, and a different process for snapping the bars in place. The head end of the E2 is available as a round-bar or trunnion design (just like the Pro Series) - I don't see an indication of which one Escape is offering.
The brackets of the E2 don't look like $275 to me, but if you like the way the E2 works then I suppose it's not a huge difference compared to the total trailer and equipment cost.
Both hitch manufacturers offer their manuals on their websites if you want to look at the details of operation.
