After you do the reading I would suggest to check the ratchets is person as they feeling varies from batch to batch, I.e . How smooth they are and the backdrag.
On 3/8 Hazet , Stahlwille and Gedore are most similar to backdrag but different teeth count, 72, 80 and 60, respectively.
I have the 3/8 Stahlwille and it is the size of1/4 of the others and very smooth so I use it instead of 1/4 in tight places
I also have the 3/8 Facom quick release which is really good and feels very strong so that is my 3/8 to go.
For 1/4 I would go for Gedore if 40 teeth is not a problem as it is the smoothest quite compact and feels good. The Gazette is very smooth but not QR and bulky. Stahlwille v compact with 80t but not so smooth. Facom I have also in 1/4 is very smooth but not QR and not slim. I have tested the Carolus Slim Sixty with 60t and it is very smooth and very slim, not sure about strength and reliability.
You could also look into Japanese Nepros, Tone, Koken.
From personal experience when tested the Proxon and Vigor ratchets they were very coarse and did not like them at but Carolus felt nice.
Wera feels nice cause is smooth but did not buy because I was told they give problems with their mechanism. No personal experience here.
I also have the older Stahlwille 1/2 inch with 60t and is very smooth but the mechanism sticks every time I undo a bolt and need smacking. The new one has 80t but if you also looking for a 1/2 inch make sure you try the ratchet to undo let's say the tyre bolt with not much force.
Now you need to the math, teeth + backdrag + strength - dimensions to find what you like[emoji1]
Don't forget after you have used your ratchets to post the details and your experience with them and other tools that may be interesting to other people.
All the best
