The problem with Trino is that it is not that easy to scale to possible RPS of Clickhouse, it introduces tons a of latency and push downs are faaaar from perfect.
Uber has a smart solution for Pinot, when they run it as a single node proxies

I wouldn't use Trino if you are looking to ONLY query a single database like Clickhouse or Postgres etc (unless you want an ANSI SQL abstraction over your choice of database). Obviously ClickHouse and Postgres will have lower latency when hit directly because you can bypass the analysis, planning, optimization and scheudling that Trino does.
It does federation better than ClickHouse and that's where it shines. Joins across disparate systems - even between relational and non-relational systems. And obviously for the MPP queries on distributed filesystems.
