Syncspider is an amazing tool. The team keeps adding new integrations, and the most amazing thing for me - is that it runs on Hetzner cloud. Hetzner has the cheapest and most stable (at least from my perspective) servers, where I keep all of my web applications. They are also least expensive, therefore the risk behind SyncSpider is very low.
One thing that was a no-brainer for me to get 10 codes - was the ability to build custom integrations with the Agency plan. You can easily publish custom integrations for everyone's benefit, or keep them private.
Here is an overview of the custom integration builder if you didn't notice this feature: https://help.syncspider.com/en/articles/4536360-custom-integration-builder-introduction-and-manual-overview
