Miswak is commonly found around Neem and Acacia trees so I can't say if there is any preference unless as you mentioned; miswak is sought by Muslims as a preference.wow thats so cool, how common would you say using miswak is in india?
where can you get these other sticks like you mentioned from?
can you tell us more about the issues with dabur please?
I just happen to google for datun sticks here https://www.amazon.in/s?k=datun+sticks&ref=nb_sb_noss
Dabur have pretty shady QC and their samples almost all fail in lab tests if done honestly. As recent as 15 days back they were found to using sugar syrup from china which can hoodwick indian standard testing. Couple years ago, there were traces of steroids in Chyawanprash.
