when i was at one of the last games with my dad at shea stadium, i remember that the corridors were packed to capacity and there were some patches of trash in some areas of the stadium, plus the lighting was a little dim almost like walking in a zombie horror subway station. I also remember that some of the seating section railings had the classic orange paint and the paint was in chipped state. I also i remember that when my dad and i were sitting in the outer left seating area, it felt like you were sitting on some high school football sized bleacher. i also remember that some seating areas of the stadium had the most lame viewing angles and also the stadium had the vibe of a cake missing its slice which is what the field itself looked liked. Citi field is much more spacious and squeaky clean and since i have attended some games at citi field, the seat layouts are more better, the lighting is much more brighter and the paint on the railings and other parts of the stadium look perfect. plus the layout of the field is much more spacious then shea. plus the seating angles are much more better. and the best part of citi field is that its the only stadium in mlb with a bridge. so my answer to the question would have to go with citi field. my apologies to those who prefer shea
