For me, I find that I like tubs most for the following reasons:
1. Tubs seem to offer the pipe tobacco in a much more reliably consistent fashion. I have had pouches that were quite atypical (extremely dry, excessively moist).
2. To me, tubs REMAIN consistent through the whole tub. I attribute this to the lid fitting well. Now, that said, I can consume a tub relatively quickly (perhaps 6 weeks, so your mileage may vary).
3. Pouches “feel” wasteful to me…. I just toss them when empty…. I have always saved and found many, many uses for empty tubs.
4. Tubs have a lower cost per ounce of pipe tobacco and I like being more “frugal”.
So, for me, I always PREFER to buy OTCs by the tub.
