VictoriaLogs will be easier to setup and operate than qryn and self-hosted Sentry. Single-node VictoriaLogs is a single small self-contained statically linked binary with zero external dependencies. It runs with optimal settings out of the box on any hardware - from Raspberry PI to high-end servers with hundreds CPU cores and terabytes of RAM.
Additionally, VictoriaLogs will provide more user-friendly query language - LogsQL, which is easier to use than SQL at ClickHouse or the query language provided by Grafana Loki.
That's inaccurare: qryn does not require SQL at all . It offers LogQL, PromQL, Tempo and other customizable APIs natively by design without requiring the user to know/learn anything.
About the easier aspect that's true - qryn is designed to be an "overlay" on top of various backends such as ClickHouse and IOx (pros and cons for each up to the user) and to provide full granular data control to the underlying set (compliance, gdpr, etc) rather than an all-in-one solution with its own proprietary formats.
