The 14 is probably somewhere between the 8 and 12 in terms of difficulty. I would say closer to the 8 than the 12. There is a good mix of assembling (albeit via regular rivets, not pulled rivets) and construction.
But don't let that deter you, while challenging, it's a lot of fun to build. You won't have a problem finishing if you've built a 12, just have your expectations in the right place.
There are a lot of previous kit parts re-used in the newer kits that need to be prepped. You can tell by the part numbers, for example, the 14 specific parts all start with "14", etc.
