You will have that issue no matter what you choose. You won't find one that pleases everyone. My opinion is you find one that runs well on your server and can be handled with ease, both for the users and the admin/mods. I had no issue with the FlashChat because we run one already and are familiar with it, both on the user side and admin side. I have no issue with the FlashIRC because we also run one and are familiar with it, both on the user side and the admin side. For us it was a win-win.
If FlashChat runs fairly decent and is good for you to administer, stick with that. If IRC is best, then stick with that. You will have to find a balance between the lag and the options/gizmos the interface provides. Users will have to make their own choice to either use it or not use it once you decide which to use. Otherwise, you two will be running around trying to please everyone until you're over 40.
Ultimately, the goal is to provide a place to chat. I'm certain you two will find something to help achieve that. If users don't want to use it, it's their choice and should not deter you.
