G4 disc, LED specification advice - larger/fewer or more/smaller?

I’m looking to buy a bunch of G4 disc, led bulbs from DX.com. However, I was wondering if I should go for larger but fewer leds or smaller but more leds?
Reason, I ask is because I recently took deliverly of a number of MR16 and G9 bulbs specifically THIS (MR16) and THIS (G9). The MR16 with 4 leds is great especially with the bezel and lens removed, very bright with (now) great spread, whereas the G9s are good but don’t blow me away. I know this comparison is not ‘apples to apples’ but you probably get the gist.

So, just you improve my chances of getting decent G4 bulbs should I go fewer but larger or more and smaller.
