With any seat you choose in section 121 you will likely be happy with it. It stares directly north at the visitors sideline and is located right on the 'out of bounds' line. The only problem could arise when everyone stands up in the rows in front of you which makes it difficult to see the back of the endzone. The sidelines also provide a better vantage point to see both sides of the field but if you ask me, you can do much much worse than buying your seats here.
I'm not the biggest fan of LP Field but it's clean and the fans have always been friendly and welcoming. I've seen at least 10 games here over the years without even being a Titans fan. I'm just a fan of the game of football and that is all.
I would also recommend that fans take shuttles to the games. The preferred shuttle service of the team is called "InShuttle" and they pickup fans from the corner of Charlotte and 10th Circle. The parking immediately outside of the stadium is usually all occupied by Titans season ticket holders so nearby parking will always be limited which is why the tailgating scene isn't all that great for games.
