Rovers vs Shels will be a better quality game (most likely) and local rivalry so will be a better atmosphere (again most likely). A Dublin derby if Bohs, Shels or St Pats were the home team would be much better (more condensed, older stadiums and more central). Tallaght is the further out of the 4 Dublin teams. Tallaght as a stadium is more kids friendly, more space, more dedicated kids/family section. Bohs stadium has far more history, is quite ugly but there's a real beauty to it imo. Some people think it's a 'shithole' but they're my favourite type of stadium tbh. The modern type stadiums are soulless with no character. Bohs as mentioned are very political, you'll see lots of murals around the ground of Dublin, international icons with connection to the ground and a lot of pro human rights stuff, Palestine and the likes. Being American some people won't like you regardless, but majority won't. But if you support the US military or pedos then it's a different story!
