Default what are the difference between this two ac delco plugs?

i have a 1995 bonneville se model and today i went to the parts store and i was looking for spark plugs, and in the computer it shows ac delco plug #41-601 for the SSE and 41-606 EXC SSE, what are the difference between the two plugs? both the SSE and the SE both have the same engines, would it matter if i go with either one? both are the same price of $1.39 a plug is one plug better than the other?

I've seen that exc thing before. I think some plugs aren't meant for supercharged engines. And there was no SSEi for a few years, just a high optioned SSE with another letter. EDIT: And some places' computers don't say SSEi.
