Carbide is my preferred, but as a kid dads wood saw we allays ran tuffnol yeah they would wear but they did just fine with wood cutting blade speed, we used lots bigger than 1/4" though.
Lots of people rate ball bearings, but me personally i find the pad contact you get with pads not bearings really seams to reduce blade wander a fair bit, just at the expense of needing a tweak and clean once in a while. properly adjusted pads and a bandsaw can be near surgical, bearings just seam to always let it move more - need way more tension to get the same amount of guidance.
