Luxeon ZES LED chips vs. CSP chips – which is better?

Hi guys,

I'm looking at getting one of these two LED PnP bulbs for my Mazda 6. They look to be identical in design and spec (lumen output), and nearly equivalent in price, but the NightEye uses Luxeon ZES chips and the Beamtech uses CSP chips.

From reading through past threads on this forum, Luxeon chips seem to be highly regarded here, but at least one veteran member has said similarly good things about the Korean CSP chips. Any opinions on which chips are objectively better? Which one should I buy? Thanks!
