Based on the odds for tickets in my area, I would take the $10 one, as it will have a higher value top prize if it is a winner. Having 2 that are worth $5 each would be silly, because it would only affect the odds a tiny bit, giving you a slightly higher but not worth mentioning chance to win $5, $10 or $25.
I would have a better deal by taking the single $10 ticket, with a chance of 1 million euros, rather than two chances at 250k.
