I’ve found the IKEA bulbs to be significantly worse than the Philips ones, so I would definitely say the price difference is warranted. The IKEA bulbs aren’t as bright, get overwhelmed if you send a lot of commands quickly (so you can’t implement a dimmer for example, without the light jittering as it dims), and don’t have the “turn power on-and-off quickly to reset to full brightness” feature (though this is nice if that’s what you specifically want).
