Nothing is proof against failure, but dynamo LED lights are closer to fit & forget than halogen (not that they were all that bad). Most problems are wiring problems, which will be common to both.
The only failure I've had since I got my first Edelux in 2008 is a mudguard rear that I bashed the lens/reflector off (still had the bare LED though), and the only other thing I've done was the squeeze the spade connectors a little tighter. Most work required is installation niggles, or replacement by newer better models.
Before that, I'd had a Solidlight that failed such that it turned off at 10-12 mph, and wouldn't come on until I'd come to a complete stop, and a rear light with a duff standlight circuit.
With halogen lights there are the occasional bulb blowouts (or 5 £5-6 p.a. cost of preventive bulb replacement), and the ability to open up the light to replace the bulb is itself is a potential cause of failure (eg a broken catch allowing the front of the lamp to fall off).
