Depends on the dims of your tank, there are also the fifty twos... Chinese vs AI, IMO, hands down AI even at a significant price difference!
You get what you pay for...AI price worth it?? debatable, but are they are well built quality fixtures, so heck yes for me! I've installed quite a few of them and I would recommend them.
Chinese fixtures came a long way, some had success and some don't. if you go that route, don't expect too much from them, especially longevity. I've seen them work well on some system, but would never recommended it. Just make sure you have a backup plan when it decides to stop working on you.
Just like the Jebao pumps. People would prefer to get 3 jebao over a vortech (1/3 the cost) but when it stopped working, they are scrabbling to find a replacement.
Just don't be one of those people that complaints when the "cheaper" stuff breaks on them
