We are currently testing Dynatrace SaaS; our server environments utilize VMWare virtual hosts and VDI's. One support group uses VMWare vCenter Realize and another group uses Dynatrace AppMon and DCRum. I like the full integration into one tool like Dynatrace SaaS. The group which uses the VMWare tool reports back that the UI and functionality is more advanced.
First of all let me link another answer we provided for a similar question from you here.
The Dynatrace integration with VMware provides ingestion of multiple metrics from either vCenter or ESXi APIs. We are not aiming to duplicate the VMware Realize UI neither the set of data presented there. We have deliberately chosen a subset of information available, that we can feed to Dynatrace AI for problem causation.
I would agree that Realize is a better management tool for VMware, while the purpose of Dynatrace is different. We are gathering data from various sources (applications, VMs, VMware APIs) to rootcause performance issues in your environment.
