I say if he likes the Boito, get him that. But as you say, the IGA Uplander is also made by Boito, just labelled IGA Uplander for the importer, Stoeger, so if he likes that variation better, get him that.
I have a Boito A680 in 12 gauge with double triggers and a straight grip stock which I bought used and it is certainly a good enough gun for the money. I looked at some new and used Uplanders and didn't see any significant difference in build quality from my Boito. (I was interested in a 20 gauge but didn't find one and I liked the other features enough to settle for the 12ga.)
