My understanding is that the majority of Methane molecules end up as CO2 anyway (Methane -> CH3 radical -> Formaldehyde -> CO2): https://en.wikipedia.org/wiki/Atmospheric_methane#Removal_pr...

So the underlying CO2 ~100 Yr+ effect is still there, but you also get a 500x benefit from Methane while it is persistent in the environment.
