This definitely a thorny subject. Initially, I hated PE. As is well known, the superglue seems to stick everything else except the part to the kit. But I persevered and got some tools, and with practice have become vastly better than early days. Simply put, if you are happy with what the kit gives you and can create something you are pleased with, steer away from PE. However, if you want a nice, neat instrument panel, for example, PE results can be stunning. Same with seatbelts. But its not just about enhancing detail that might be already present, but adding detail left off. For example, I'm currently adding on the superb detail set from Atlantic to Airfix HMS Daring. This includes beautiful antenna array that improve the kits, but also railings and other parts that are not present. It has nearly driven me to an early grave, but I can see the final result will be impressive and an enormous sense of satisfaction.
