Google "pruning tomato suckers" and you should find a lot of useful information. Many people feel that pruning tomatoes - especially in more humid locations - helps to improve airflow (and thus reduce fungal issues), and that pruning can also improve the size of tomatoes (if not yield). Of course, there are others who don't prune, whether they don't believe in pruning or their gardens are too big/they just don't have the time to prune. It's all a personal preference.
Me? I prune my tomatoes. Sometimes I miss a sucker early in the season and, before I've realized it, I have a much bushier plant than I'd intended, but it's not a big deal. My pruned plants certainly grow taller than the non-pruned ones (e.g. I have a Jersey Devil nearing 9' tall right now
), and I feel like I get a better yield from my pruned plants, but I can't be 100% positive on that.
