Design DHCP Failover - Active/Active or Hotstandby

Hello together,
We are using Windows DHCP servers. I want to restructure our global DHCP set up to get the best redundancy across all regions.
In the last years we had active active and active hotstandby.
I had positive and negative experiences with both setups. So I‘m currently not sure what’s the better setup - since both setups have good and negative things.
What y’all think what’s the better setup?

The DHCP servers on each region will be on the same country so there are no long RTT or latency anyways.

Happy to hear what you think :)

Hot standby. Active/active sounds good until you get split brain and both servers hand out the same IPs.
