Well, I guess we are all different but in almost 30 years of aviating I have flown troop transport (VC10), corporate (HS125), IT (B757) scheduled pax (B757/B767) and freight (B744) and, without doubt, freight is the most enjoyable and diverse flying I have ever had.
You can be away anything from 1 day to 20 days and rarely complete a pattern without a change here and there to your roster. Some people like it, others don't but I love it.
Hope that helps.
