I think most of the ones on the list, you could throw a dart and do well if you know how to train well. We even get light burn on old tech HLG 550 V2's if we're not paying attention. (Samsung 301b diodes). And it's true that 10 year warranty is a mute point. Technology is going to get better and better every year. The thing with LED's is that they last forever with no maintenance. I'd just look for the one that fits your needs the best as far as footprint, PAR, heat dispersion, and forget about warranty.
