A high NAV scheme usually indicates that the scheme has performed well in the past, but there is no guarantee that the scheme will perform equally well in the future. Similar a scheme might have a low NAV simply because it was launched relatively recently and not because it was it has performed poorly in the past. In this case too, there is no guarantee of future performance. So, neither the high NAV fund nor the low NAV fund can be considered as a better choice. You need to consider factors like the type of mutual fund scheme, investment style, your investment goals, your risk before making the investment decision. Whether your chosen scheme has a high or low NAV is actually not a good way to choose investments.
