Nano,
Check if the educational qualification has an equivalency option i.e. MS EE or equivalent. Maybe your qualification will then fit in the substitution requirement.
I would recommend tha you take the subsistitution option over the other two options. For one, if things click then you are better off, if things dont click you always have the other two options, but at a later date.
Again all this depends on how much time you have left on your H visa
Waiting for perm, at this point, is definitely not a good idea. Non-rir filing is a lot of uncertainity over a long period of time. If you can live with this uncertainity, then it is a good option.
