I defer to your experience. I've never used wire bail jars, only mason, for cost reasons.I have experience with both, the mason jars are much better. What I found out with the wire bail jars is you had to be certain to perfectly center the lid before clamping or it could leak. Bottom line, tobacco left in 3 wire bail jars dried substantially in a years time. Perhaps your experience has been different, that was mine with all three jars.
