There's a good amount to understand why mars and via are poor performing; this somewhat will scratch the surface to understanding some of the measurements behind them;

Also lets say they claim its a 300 watt (equal to 600w hps claim) light by saying that it has 30 pieces of 10 watt diodes. (10x30=300) Which sounds like it makes sense. But it only pulls 135w at the wall. That means its a 135 watt light, not 300 watts. A watt at the wall is a watt reguardless of how many diodes or whatever. Those blurples can be misleading on top of their poor performance. (Again, this is all from my limited understanding, so maybe take it with a grain of salt)
Lots of people unknowingly buy these lights just because they hear how good led is, but that doesnt make all leds equal. They aren't bad for clone and seeds (blurples only use imo, although not worth the price compared to t5's) as theyre rather weak and seeds/clones don't like a lot juice off the bat.
Now, as for a recommendation; I just ordered 2 kits of the 3000k for a 4x4 myself just because they're so easy to assemble in comparison to strips and cobs because the parts list is already picked for you.

3000k option is best suited for veg and flower, 4000k is typically only for veg.
Minimal assembly, dimmable, and great PAR spread because of the board design. Basically plug and play, especially if you use the prebuilt option. This is probably one of the the easier options if you're not overly electrically savy like myself, no guessing or numbers, they did it for ya, just assemble, plug, and go. I believe there's also a video on youtube for assembly which is rather easy if you dont go the prebuilt route and want to save that 70-75 bucks or whatever it is.
Heres a cob kit if you decide to go that route;
They're in the same ballpark as far as price
