GlitchTip is very simplistic and miles away from Sentry.
We really wanted to keep using it, since it was easy to selfhost, but the UI was not giving enough information from a dev perspective to be very useful : grouping, filtering and labeling issues is very basic, which prevents understanding.
We decided to self host sentry, which is an absolute beast to deploy, the open-source helm chart is nowhere near production level, and the underlying technologies are quite hard to maintain (Kafka, zookeeper, clickhouse...). We had to work on it constantly for two months to stabilize it, and now fear the moment we'll want to update. The dev teams love it, so it was worth the hassle!
This is something we're (Sentry) not happy about. Always hard to maintain the simplicity with growing product functionality. There's efforts underway (e.g. https://github.com/getsentry/self-hosted/issues/1763) to reduce the footprint if you only need portions of the functionality.
