The only way to truly become comfortable in IMC and/or IFR training is to immerse yourself in the knowledge and skills. IFR6 has solved the problem of "half-assing” the process. Allow me to explain, you dedicate the time (6 days) you show up and fly, whether it is the simulator to test and repeat your areas of weakness, or being around the A grade instructors to learn from them. Flying in IMC and being able to apply these skills learned in IFR6 makes you a better pilot! In my opinion every private pilot should be required to go through IFR6 it is the only way to be an IFR pilot who is confident in IMC.
