I love my SO pears. My 1/2" is an older made in Canada model that is probably a 20 tooth. I rescued it from a used tool store for $20. SO dealer rebuilt it for me and I cleaned it up. Love the feel of it and it's as tough as nails. I also have a newer SO 3/8" pear, that has is much smoother. I bought this one used, but it's in like new condition. Great for tight places (lots of teeth), and has a great feel and good styling.
In my track box I have an older Gray 1/2" pear ratchet, much like the 1/2" SO it doesn't have many teeth but it's tough as nails. Also in the track box I have a 3/8" Bahco with a rubber grip. Look's futuristic and works great, # of teeth is between fine and course.
Those 4 are my "go-to" rats. For 1/4" I have 2 different (Danaher) Kobalt pears I use, but I'm not as keen on those, don't like the lever style or the handles much. I probably have a dozen other ratchets in brands ranging from Mastercraft to SK but they rarely get used.
