I have played with all sorts of bearings and some of the "best" bearings were the cheap bearings. Some of the worst bearings were the cheap ones. Lol
The most consistent ones, at least from Daiwa and Shimano, are their stock ones in the mid to high end reels. Out of the box the boca, spoolspeed, fasteddy are without a doubt the best. BUT, when stock bearings in those mid to high end reela are flushed and properly oiled they compare to the more expensive bearings.
After having played with bearings for years in my reels and tearing them down I am amazed so many people push to change out all your bearings to high end. In fact, many places, like the worm gear, imo, should not have bearings. It's a low load application and doesn't see high end speeds that even warrant an abec7 or 9 ball bearing - bushings serve the best purpose here, can be hydrophobic and won't corrode. Last year I cut out some bushings on a lathe to replace the drive gear bearing on a couple of my reels and the results were very satisfactory. I tried out some rods of UHMW.
