For the Hunter my own preference would be whichever tour takes in more smaller boutique wineries. Wherever you go there you'll be treated to great wines and knowledgeable people, but at the smaller places you'll be more likely to be tasting with the owners of the vineyards who will have a passion for what they are doing, rather than employees of a big company. For example, McWilliams have some lovely wines (my favourite is the Elizabeth Semillon), but if you visit Marsh Estate (long time ago, it mightn't still exist but just an example) you'll likely be talking to Mr or Mrs Marsh or one of their adult kids and you'll try some wines that you won't be able to taste or buy at every bottle shop in the country.

I was born and raised in Katoomba, so it's hard for me to comment on a tour to the Blue Mountains. If it's a day trip, I'd tend to do the one that fits the least in, a trip to the Three Sisters and Scenic World or whatever it's called these days is probably enough, a long leisurely stroll through the valley at the bottom of the Scenic Railway is great. The food at Scenic World is nothing to write home about, so if that is a selling point for any of the tours then ignore that! A meal at one of the pubs in the Mountains would be great - Grandview at Wentworth Falls, for example. All thing being equal I'd probably go for the tour that has the most comfortable looking seats on the bus, if there are traffic problems between Lawson and Katoomba you might be spending quite a while in your seat.
