I agree the ideal is both.
But if you could choose only one, pick rollers.
The idea of adding resistance to rollers is good on paper, but if you start doing high effort intervals on rollers, your form WILL suffer (even just a little) and you WILL fall over. It's not dangerous, since you are going at 0MPH but it is still annoying.
