IMO it would be a toss up between the picco and the vspec. not taking anything away from the hyper engines they are great little budget mill's. but you just cant compare them with a high-end engine. on the other hand, if you are just starting in nitro then the hyper might be a better choice for you. not only is it easier to learn to drive with a slower engine, its also better to learn to tune with a low cost engine. that way you wont waste a $300 one.
