Which veterinary hospital would be better? VCA or WSU?

My cat has a tumor in her head, the only way is to take radiology treatment. And in Washington, there are only two hospitals that can serve it.

The first is WSU, but I searched online and found that they don’t have SRS or SRT treatment. And my cat took really a long time (24h) to recover from the sedation last time when she took CT. I’m really worried about that.

The second is VCA Northwest Veterinary Specialists. They can serve SRT, which seems to be much better for my cat (less treatment times and recover quicker). But I found there were so many bad comments online, I’m not sure whether this hospital is reliable.

Does anyone has any experience or can give me some advice?

Really appreciate for your help.
