I see some people asking "Why should I use your TAA when ETS2/ATS has it". Lets check with some comparisons.
1080p 120 FPS Comparisons (same vehicle speed for in motion comparisons)
TAA Soft (Native), 0 Sharpening vs TAA Clarity by Snowy Moon, 0 Sharpening (In motion)
TAA Sharp (Native), 0 Sharpening vs TAA Clarity by Snowy Moon, 0 Sharpening (In motion)
TAA Off vs TAA Sharp (Native), 0 Sharpening (Stationary)
TAA Off vs TAA Soft (Native), 0 Sharpening (Stationary)
TAA Off vs TAA Clarity by Snowy Moon, 0 Sharpening (Stationary)
TAA Off vs TAA Sharp (Native), 0 Sharpening (In motion)
TAA Off vs TAA Soft (Native), 0 Sharpening (In motion)
TAA Off vs TAA Clarity by Snowy Moon, 0 Sharpening (In motion)
Also even with TAA Soft option there are a lot of leftover flickering/shimerring in motion. I hope this helps you to understand the difference. You can try in game and see the difference yourself.
