If the figures stacked up, would you get a repayment mortgage over an interest only, or would you always opt for a interest-only policy?

I'm under the impression that most investors go for interest-only mortgages for 2 main reasons:

1) the monthly payments are cheaper
2) you don't need to pay income tax on interest-only mortgages

Would you agree? Anyways, as an investor, which type of mortgage do you think is best?
