During the evaluation phase, my company considered products like HCL AppScan and a product from Synopsys.

We did evaluate AppScan for this task. Both solutions are good. We also evaluated Oracle of course, but it is purely a SaaS solution and that's the reason it was not considered.

We used Acunetix and Netsparker with Burp Suite.

No, we did not evaluate other options.

I have been told by friends and colleagues that Acunetix is better, so I will be evaluating that solution in the future.
