Do you not know how fast ( or not) they reimburse? It may be that you won't be paying interest if you get the check fast enough...

I'd use the credit card, but I would be very careful about making sure that you get reimbursed right away and that you pay your credit card that amount plus whatever you usually pay (if you don't pay the full balance). You don't want to create a situation where you increase your credit card debt because you spend the reimbursements on something else. It's easy to think it's "extra money" when you get those reimbursement checks.
I've found YNAB to be very useful in keeping track of and categorizing credit card purchases, as well as keeping track of reimbursements related to my work.
