I actually enjoy both. I believe the traditional Reuben sandwich is made with corned beef. However, my understanding of them both is rudimentary and limited to Wikipedia. ? But my basic understanding in their difference is how they are cooked. Corned beef is boiled and pastrami is smoked. They are both brined beforehand. Additional seasoning is also put in that brine (which is basically salt, water and sugar) where it soaks for a long period of time. Then more seasoning is added to the pastrami before it is smoked. They are usually from the same cuts of beef (the brisket cut) but I also read that pastrami can come from other cuts as well.
6 slices rye bread (dark or light) divided use
1 pound thinly sliced pastrami or corned beef divided use
1 14.5 oz can or jar sauerkraut drained well

Place remaining slices of rye bread into food processor and pulse into fine breadcrumbs and set aside.

Cover evenly with half of the pastrami.
Then evenly top with drained sauerkraut, chopped pickles and 1 tsp. caraway seeds.
Sprinkle 2 cups of shredded Swiss cheese on top of sauerkraut layer.
Next, top with remaining pastrami. I gently push down to help compact it all a bit.
