I have noticed that the quality of the slo mo footage at 240 fps - 720P is quite poor on my X.
120fps at 1080P is only marginally better. Is it just my unit and I need to get it checked by a genius or is it normal?
I don't recall my iPhone 7 being so poor.

What aspect of the video do you consider to be poor? Clarity? Smoothness? Color? Brightness? Do you have an example of the slow motion footage you find unacceptable uploaded somewhere?

Without knowing any details, we can only make assumptions. My guess is the slow motion video was shot in a dimly lit location and/or a lighting system that has caused a strobing effect.

And also that the OP is not using a X side it can not record 720p @ 240fps.
Maybe the OP is using some 3rd party app that allows it and, if so, should specify such.

Video quality is poor using 240 at 720P
As if one was shooting with a 3GS.
Resolution is poor in comparison with normal video at 30 or 60fps.

Perhaps it’s a bug that it’s showing up for users with a certain setting and so it has not been properly tested? Why even shoot in 720p anyway and complain about quality? Just do 1080p. Obviously OP doesn’t care about storage space since they’re using the non-HEVC mode.

I don’t think it’s a bug, if you look at the storage usage the 720p takes up more space than the 1080p 120fps on high efficiency. So I would imagine it’s there as an option for people who are like me haha and a couple others here haha.

Ehh, I know for me the reason I have it set that way is just my use case.

A: I rarely shoot in slo-mo (could be argued why not use 1080p then)

B: My iPhone is the 64GB version with about 30GB of music and 10-15GB of apps.

C: I don’t use the new formats because they are currently only readable on High Sierra (maybe some specialty sw as well, but not that I know of) and my Mac is on El Capitan and I prefer to keep my photos and videos as universal formats.

C: You do know that the iPhone converts the videos when you send them, right?
