Deinterlacing advice, which looks better?

Not sure if this is the correct place to post this but here goes.

So the reason I'm making this post is cause I am visually impaired so it's hard for me to tell what to look out for when comparing deinterlacing filters and their results as well as details like artifacts in general.

I have a video that is recorded in 1080i50 I would like to deinterlace into 720p50. Based off of some research I've largely used QTGMC for deinterlacing to 720p50 and NNEDI3 for single frame rate deinterlacing.

However it was suggested to me that I try using yadifmod2 as QTGMC can introduce shimmering into double frame rate video (or at least I think this is called shimmering, I'm referring to when you have something static like a logo that appears to be quickly moving up and down each frame)

Here's a 10 minute sample that was deinterlaced using QTGMC.

Here's the QTGMC call in the script, note I'm specifying the values of Rep0 and Rep2 in an effort to reduce shimmering without losing quality.
QTGMC(preset="Slower", Rep0=0, Rep2=0, EdiThreads=4)
Here's a 10 minute sample deinterlaced with yadifmod2


Here's the yadifmod2 call.

And here's a 10 minute sample of the original source (ignore the FPS reported, that's just cause I trimmed the sample from the original source using LosslessCut)


So which of these looks better in your opinion (as in more visually appealing, not necessarily more accurate to the source)?
