For the most part they are the same, but here are the differences:
JRS Iden and JRS Gideon are missing this bullet point, but Spec Ops Del Meeko has:
Helmet is specific to Inferno Squad, but modeled after the Rogue One Tie Pilot Helmet.
JRS Iden and JRS Gideon says:
Helmet may be light to moderately weathered.
Spec Ops Del Meeko says:
Helmet may contain lightly done silver weather but it is not required.
The first bullet point difference is an interesting one but honestly, a side by side of all the CRLs on the helmets look the exact same. Obviously the 2nd and 3rd major bullet points above don't matter because the Del Meeko one says not required, so lightly would be good with the JRS ones, if any weathering.
I'd also double check with your GML on top of what you have here to make sure since they will be the one to ultimately view and make the determination.
