I don't buy tobacco based on cut, however I found I was never disappointed and always pleased with plugs, flakes and ropes so I tend to stay with them. I think the blenders/producers put extra care on these cuts given the extra work involved in the production and likely use better tobacco quality which ends up in superior products. An additional advantage of these cuts is that they burn slower so they are great for small bowls, as well as they are better for outside smoking.
Said that there are also some very good ribbon cut/shag cuts and I enjoy them as well.
