I have a mix of normal Hue bulbs and some Innr brand GU10 (spotlight) bulbs. The difference in quality of light from both brands is quite noticeable, with Hue being far and away better in terms of colour blending and accuracy. There's a reason the Hue bulbs are 2-3x the price of the competition
That said, I've had multiple Hue bulbs either outright fail or one LED die so that it still works but the colour is completely wrong. It's frustrating for bulbs that are supposed to last decades but maybe the latest generation are more robust.
They're also regularly on sale for Black Friday and the like, so I'd advise planning your purchases around those events.
I wouldn't worry about leaving them on. Standby power draw is very low and I think even at maximum output they use about 7W each. It's just not a big deal.
