Never tried those, but speaking about flicker, some LED lamps flicker not because of the mains frequency (50/60 Hz depending on where you live) but because of their internal switching power supplies.

It's mostly a crapshoot even within the same model line. Even under "Philips UltraDefinition" some styles have high flicker while others don't. I'm not sure being dimmable is any guarantee of smoothing quality, in fact dimming is usually implemented with PWM as I understand so the easy solution to avoid flicker of chucking a smoothing capacitor on there might make it harder to implement dimming. (To dim properly without noticeable I think you'd have to PWM in the kHz range. Even cheap CFLs necessarily had the technology to operate on this frequency, for some reason it seems rare for LEDs to do it.)
