The difference between the oil filled radiator and the forced fan heaters is a personal preference. I am always cold in a room with an oil filled heater - unless I am sitting right on top of the heater I don't feel its heat. With a forced fan heater, I can feel the heat. I can be further away and still benefit from it.
For another person, it's the opposite. For the OP, try them and see. If you like the forced fan, I find the tower style works better for me as it pushes a wider path of hot air than the small ceramic ones. I got one with a remote, so I can turn it on and off without having to get out of bed.
