I'm not yet of RMD age. When I get there, if I still have anything in my tIRA, I will most likely take it out (or use it for QCDs) early in the year. Otherwise if I died during the year that would be one more burden for the executor to do.
Besides, if you put it in a taxable account you might be able to limit taxes by investing and holding for LTCGs, or investing in something that pays qualified dividends, or investing in tax-free municipal bonds or something like that. If it's in a tIRA, it's all taxed as regular income when you withdraw. So I'd rather take the money out of the tIRA early and let it grow in taxable with possibly more favorable investments wrt to taxes.
If you like the concept of monthly "paychecks", do 1/12 each month, but leave good records for your executor. But also consider that you could withdraw the whole RMD in January and put it in an investment account, and set up auto withdrawals from your investment account each month into your checking account.
