I have a nanlite FL20g, and while it isn't optimized, from what my eye could see, it did a good job. At least in terms of getting it to be spot instead of flood. I should find an affordable light meter and just invest in that, then I could be a little more accurate in my thoughts. Looking at getting two of these Colbor reflectors, I have some of their 100 watt lights and they do a good job. https://www.bhphotovideo.com/c/product/1736566-REG/colbor_colbor_bhr55_55_degree_hyper_reflector.html
But overall, absolutely for the price these are great. They're bright enough I'm blasting them through a cloth/softbox or bouncing them off something, so I'm gonna get some color shift anyway; and like you said, they'll go a little green as they get older too. But I'd rather have a little more magenta in my skin than green, that's for sure. Mostly because I'm ginger and incredibly pale, so the magenta makes me look a LITTLE closer to normal 😂
