para has lower recoil overall, and is much more versatile (especially if you're into competitive gaming). the para's crosshairs also tend to bloom much less compared to the ebr.
the ebr on the other hand takes a minimum of 3 shots to kill close up compared to the para's occasional 2-hit kills. ebr shoots much more slowly so you're likely to get outgunned by most guns despite the ebr's 46 dmg.
however, the ebr has a longer one-hit headshot kill range.
So basically:
the ebr is a poor man's para with lower dmg, rof, stability, and mobility, but with more range and crosshair bloom.
