Chihiros WRGB II vs Twinsta V S-line?

Hi, I’d like some advice. I have a 90×45×45 cm aquarium and I’m looking for a light that can be hung above the aquarium. Currently, I’m using a Twinstar 900S 65W (2nd generation).

I’m considering either the Chihiros LED WRGB II 90 100W or the newest Twinstar V series 900S 100W. Price-wise, they come out about the same. I know Twinstar is really high quality and uses excellent LEDs. Chihiros is definitely good as well, especially since it’s used by Green Aqua and others.

What slightly favors Chihiros for me is that you can add a shade to it, which isn’t possible with Twinstar.

Could you help me decide? Thanks a lot.
