In Newark I grew up on Bragman's over on Hawthorne ave (Charlie special was my go to). Hobby's on Brandford Place downtown is another staple in Newark. (I always preferred their burgers more so then their sandwiches). Never messed with Coopers too tough. Especially the spot on Grove st, where they had the feens nodding off, handling the meat 
In NYC Katz hands down got the crown imo. I always get the pastrami reuben on a roll when I head over there. They have a smaller version of Katz over in Albee Square if you don't wanna deal with the hustle and bustle of the main spot. Speaking of Brooklyn, you got David's on Nostrand which is ok but they're hit or miss imo. I only been to 2nd ave deli once but that was over 20 years ago so I forgot how their pastrami is.

Just googled because you mentioned Nostrand, Never knew the name of this spot always referred to it as the corned beef spot down the block from my aunt crib, I haven’t been there in years tho
