I'll miss the VS Little Red services when they go. The one I use the most is LHR/MAN which is coming to and end in a few weeks. I've had some terrible luck the past six months or so with services being delayed in both directions though (but I've had the same on BA too on this route).
Overall the VS experience is on a par, if not a nudge better than BA (I'm Gold with both so the benefits are similar) but the ticket prices are usually substantially lower with VS. In addition, getting 2,000 VS miles per flight is a good bonus as is the redemption cost on the domestic routes (1,250 VS miles plus £17 per flight for VS as a Gold).
