Help me decide on which case to get for my next build

I'm planning my next watercooling build but can't decide on which case i want to build in. Judging by the amount of builds posted here with the Lian Li PC O11 case its a good case for watercooling. I'm also looking at the Thermaltake Level 20 XT case, which looks like it can also work really well for watercooling. Any opinions on these cases, material quality, ease of building in, etc? Other cases that may be worth a look at?

I have previously built in a Fractal Design Define S and a Fractal Design Arc XL, and while they are both decent cases, they do get kinda small when you put in several radiators, fans, pump+res and tubes on top of trying to do a decent cable management. Both the PC O11 and the Level 20 XT cases looks like they have plenty of room for that.

The parts going to be watercooled will be a Ryzen 9 3900X and a Radeon RX 5700XT. The motherboard will be an ASUS Crosshair 8 Hero. The VRM heatsinks on that board looks decent enough, so I dont think I'll get a monoblock for it.

2x 360mm radiators should be enough to keep this cooled, right?
