Well, the thing about TNG is, it doesn't matter where in the series you start, but after you start you should watch them in sequence.
So, 5-6-7-1-2-3-4 is just as good as 1-2-3-4-5-6-7. But both are better than jumping around randomly. Which is why I personally recommend Q Who-3-4-5-6-7-1-rest of 2.
It is true, maybe 1 out of 10 Star Trek fans finds VOY or ENT to be the best series, but I'd bet a majority of those people watched another Trek series first and then watched VOY and ENT.
