1) Subjectively (my preference actually) using my eyes: Open the script below in a player like MPC-HC and step through the interleaved pictures one by one and spot the difference.
Code:
v1=your source filter for videofile 1
v2=your source filter for videofile 2
interleave(v1,v2)
Pay attention to fine details (especially in low contrast areas), blurring, color banding, noise, artefacts etc. Step backward and forward between pairs of pictures. Zoom in as needed.

2) More objective: Using a standardized metric. Google for PSNR, SSIM, VMAF to get an idea how to proceed. And crop the borders for these tests because they would bias the result.
