<prompt> Human: My wife has started a new job and will finally have a 401K available to her. Ive had my current one for 12 years. Is it better to contribute more savings dollars into one account than the same dollar amount split between two accounts? My account is 100 vested and has a bigger balance obviously. Trying to decide whether to increase my contributions and keep hers equal to her employer match vs. keep mine where it is and have her contribute more. Thanks  <response>: Who will retire first?Who has the best fund options?
