Google BigQuery vs. Snowflake
Which Cloud Data Warehouse is the better one?

To take out a bit of suspense, I will not test both systems with certain SQL queries and show you at the end which one is faster and you or your company should buy. But I will show you the differences and where the strengths of each system lie in.
Both systems are designed to make large amounts of data easy to analyze in the age of Big Data. While BigQuery is a Google tool within the Google Cloud Platform, Snowflake has an open structure and can be operated on all major providers.
Scaling and Computing
The two systems can scale very well and can work with Big Data. While BigQuery does this automatically, Snowflake is giving you some configuration possibilities. BigQuery and Snowflake both scale very well for data volumes and query concurrency. The decoupled storage/compute architecture supports resizing clusters without downtime, and in addition, supports auto-scaling horizontally for higher query concurrency during peak hours [1][2].
Performance
In addition to scaling and concurrency between users, the performance of the individual queries is also an important factor in modern Data Warehouses. Who likes to wait minutes or even hours for results these days? As I said, I will not test individual queries here and then say what is better, since this can be rather difficult, because it can often differ depending on data type, region, architecture and lead to different results. But if you read other sources and also from my experience so far, both systems work quickly and reliably [1][2].
Support for Use Cases
Here too, both systems are on an equal footing. Both support classic data warehousing with Self Service BI and SQL analyses. But they also offer interfaces to Python Notebooks and ML Services. BigQuery might have a slight advantage here, since it can be easily combined with other Google services and even offers machine learning via SQL with BigQuery ML [3].
Conclusion
Perhaps disappointing at first, I do not say which solution is better. In all three categories the solutions are about the same. For me, it depends more on the use case. If you want a platform-independent Data Warehouse with more configuration possibilities, you might lean more towards Snowflake, while Google Cloud users, who also want to have little maintenance effort, might lean more towards BigQuery. However, it has to be said that Google has created a solution with BigLake (Read here more about it) that allows data to be analyzed via BigQuery across platforms, also in Azure or AWS. This decreases the advantage of Snowflake a bit, but also shoots against solutions like AWS Redshift and Azure Synapse. You might also be interested in the following links:
