Ultimately NagiosXI is the better solution than Core but shortlisting NagiosXI also definitely depends on the infra landscape, technology, network devices, and other scopes of activities in monitoring.
The biggest difference I see between Nagios Core and XI is the user interface, reporting, and onboarding any element for monitoring, and that onboarding is much easier in NagiosXI than Core. Nagios Core is little complicated where you have to use console called Nconf or editing conf files in Linux needs more technical knowledge than using NagiosXI.
