I have flown at both BFC in the old days and did my CPL/IR at PAT. The difference between the two is getting smaller.
Both have professional instructors, the up side for PAT is that they only do CPL/IR training and it shows. At BFC you get the mix of mainly PPL students and some CPL/IR students (maybe that changed with the ending of SFT...) If you get Lance or Miles as instructor than I think you get what you want: excellent instructing. Don't know whether they use hourbuilders to instruct at BFC but with all respect that is not what you pay for.
All in all BOH is still a great place for commercial training and a full recommendation for PAT. Recommendation for BFC if you get one of the "heavies" as your instructor. Good point for both is that they have a pay as you go scheme! Accomodation at BFC is slightly better (portocabins vs WW2 buildings) but hey you want be in the Duchess (which they both operate!) anyway <img src="wink.gif" border="0">
