I say if you can afford to buy it, and it would be worth it to you if it does what you think it should, try it
! If it doesn't work out for you, I'm sure you'd have no trouble "destashing it to another HG member. I, personally plan to buy the BBM ultimate kit soon. Everyone's different, and I think it has a lot more to do with how you process instructions/direction than which is "better". I have researched all the template kits to the point my head hurt.... the NBNG and BBM both have great reviews.
Good luck, hope it works out for you. Either way, don't give up
