Based on the poll, I'm in the minority here. I find Latias to be a favorable design over Latios, and although I use Latios more often in competitive battling due to its superior offensive stats and movepool, Latias has a special place in my heart because I caught her legitimately in Sapphire, after a long and frustrating hunt. Not to mention that she isn't too shabby when it comes to competitive battling as well. She's used for her defensive capabilities, which I enjoy more than an offensively oriented team. Unfortunately, defensive Pokemon don't have as much success, and so Latias doesn't find a spot on most people's teams.
