I tried about 15 different makes of 35W-50W GU10 halogen replacement LED spots (3W-6W) and through trial, error and quite some cost I've found that the only superb replacement comes from such and unsexy company as Philips.
These are fully dimmable with a dimmer meant for LED-lamps (note: you can fool a capacitive load dimmer with leaving a single normal halogen lamp on the circuit - because LED's have an inductive load traditional dimmers won't react to the them by themselves or react sluggishly.) and provide a real drop-in replacement with the 40-deg angle of light. (Most cheap LED-spots come with a 25-deg light angle so they are mostly useless in room lighting)
Check out The suggested dimmers list from Philips.
I prefer the Warm White (2700K) variety which is quite close to normal halogen spot colour - the cold ones feel bluish.
I've replaced around 50 spots around our house and I've encountered one broken Philips one in the last three years and it blew up when the power was cut due to a storm so it might have been a power spike and not wear.
I can't say the same for the chinese and non-brand ones I tried prior to giving up on cheaper alternatives and tried Philips ones (£50/pcs at the time). So with them costing a measly £20/pcs today I don't see the point in stacking up on old lamps. The imports from China (DealExtreme ones either had a bad thermal design (over heats and breaks
