Guild Wars 2

I plan on making a Charr (my first) so I can get the storyline achievements. Without giving away spoilers, which creation choices lead to the best personal story?

Choose Dinky and pay close attention to his lines that he spouts during the personal story.

Dinky is a good choice for some amusing lines.
Euryale is neat for comments about the lack of trust in magic users within large parts of Charr society. And for telling it straight.
Reeva’s perhaps not as funny as Dinky but it’s sometimes nice to have an upbeat partner in crime.

I don’t have experience with the other two.

As for the other choices, I’ve liked them all. I am a big fan of the charr culture. I might be inclined to go with "Sorcerous Shaman" for a little more GW1-flavored Charr experience, if that might matter at all.

Having played all three father lines I would personally recommend the shaman father. When it comes to Legions, I can’t really say, it comes down to your personal taste on what “play style” fits you or your character. I think they are all equally good and have enjoyed all 3.

I preferred the Gladium father route. For Ash/Blood/Iron, I found Ash to be the most interesting due to the espionage nature of the line.

I liked Blood Legion the most, personally, due to the mission where you command your warband. It was the only mission where you really felt like you were a legionnaire.
