My two cents - "ease" of upgrade is more related to planning the OpenStack components setup than to the deployment method
An alternative for bare metal is use a couple of servers as KVM hypervisors to host management VMs (Keystone, Cinder etc) and install Nova compute on the other ones, automating with Foreman+Puppet
Yeah....we use intensively puppet. But that's not solve the «problem» with openstack. Long time ago (few years) when upgrading openstack they are lot of thing to do (change of config etc.) and the main issue is when you deploy with “apt install” (through puppet, manually or ansible or what-ever) it's complicated or even impossible to revert. For example when Debian upgrade xxxx from version a.b.c to a+1.b1.c1 and broke something in openstack we are in deep s*t.
