Which LEDs ?

I just bought a cheap 2$ 6leds 3x AAA flashlight and damn, it's very good for the price. Might buy more and switch the leds..

I'm looking at BestHongKong leds, I bought from them like 3yrs ago and still have 20+ leds left but they have new stocks...

10mm White led : 100 000 mcd
10mm Pure White: 60 000mcd
5mm White leds : 40 000mcd
10mm High power 4chip @80mA: 825 000mcd* ???

Which one is the best? I don't understand their claim for the 825 000mcd, look more like 18 000mcd x 4 chip, no more...

Thanks
