I use the Olfa blades, but always look for a good deal, stock up on sales, that sort of thing. I'm one of those Harbor Freight drop out's, mainly because I had to put so much pressure on the cutting blade to get through the fabric that it was chewing up my cutting board. I also have some titanium blades (a birthday present from Hubby), and I have to say I adore them. Light pressure cuts through anything, IMHO. I also second the Martinelli brand. I used one during a "group quilt" and it was light, well balanced and cut beautifully. I haven't been able to afford to buy one for myself, but I will when I can.
I can tell you that the Martelli blades do not fit in my Olfa cutter, because I tried. But if I switched to Martelli I'd get the cutter as well because it feels so nice in my hand and makes cutting easier.
