The short version

Only Checkmk has a free tier, so it costs nothing to try first.
Each has a real cost: Checkmk pricing calculated by service count, not hosts (approximately 30 services per host on average); Finxact fiserv sells several core platforms, so a buyer should demand written investment and support commitments for Finxact specifically rather than trusting that the surviving brand implies a protected roadmap.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Checkmk

Pricing calculated by service count, not hosts (approximately 30 services per host on average)
Professional support limited to 8-10 hours per week on base plans
Synthetic monitoring is separate add-on with per-test pricing

Finxact

Fiserv sells several core platforms, so a buyer should demand written investment and support commitments for Finxact specifically rather than trusting that the surviving brand implies a protected roadmap.
Core migration is a multi year programme where the licence is a small share of total cost against integration, data migration and parallel running.
Buying the core from Fiserv strengthens a relationship that already covers cards and payments, which weakens your negotiating position across the whole estate at renewal.
It is a United States product with United States regulatory and product assumptions, so international banks get little from it.
Being part of a very large vendor changes the service experience: the responsiveness that made Finxact attractive as a startup is not guaranteed inside a company of Fiserv's scale.
