Like sibling comment mentioned, Fusion. Was using it to deliver advertising video VFX work on the daily for a couple of years, it's great. We were a mixed group of After Effects and Fusion (and many more apps) users and I would say generally you can accomplish the same things with both and some tasks are easier in one or the other.

I would recommend downloading the standalone Fusion Studio though, it's included with a Resolve Studio license (~$300 one-time). Managing anything but the simplest project within Resolve's Fusion page seems like a nightmare. Being able to use a separate app that saves its own files is a much more straightforward workflow. Then check out VFX Connect if looking for more sync between the apps.
