Is there two different options for an Apple Watch SE?

Is there two different options for an Apple Watch SE? I have seen some say APPLE WATCH NIKE SE & other just Apple Watch SE. I just want to understand what is the difference between the two if they cost the same.

i really want to use them for my workouts, meaning, how many steps a day, how many calories burned, heart zones (peak, cardio, fat burn) & for sleep info. I have used fitbit everyday since I bought it 4yrs ago but am trying to switch to an Apple Watch and don’t want to be disappointed. Can anyone give me a little more info
