I'm looking at some of these for Xmas, which are brightest and best ones now adays?

....Brightest? - Do you mean whitest? I would have thought that the quality of a good automotive LED DRL isn't judged or measured by its brightest. Good quality, not cheapo stick-on, DRL's are bright enough without irritating other road users by dazzling them. Be seen but don't dazzle - You don't want to be lit up like a Xmas tree.
Best? - That's very subjective, but I would look for those brands who also manufacture for OEM production cars - They build to higher standards and to practical requirements such as weather resistance and durability. My Hella's have been awesome.
I saw a car the other day with obviously cheapo low quality LED strips and 2 bulbs had gone on one side. It's looked the absolute opposite of cool.
