Comparing Lacework alerts to native AWS GuardDuty - fewer false positives?

Hey everyone, I'm still pretty new to cloud security. I'm using Terraform to set up a basic AWS environment and trying to understand the alerting landscape.

I've got GuardDuty enabled via Terraform like this:

```hcl
resource "aws_guardduty_detector" "primary" {
enable = true
}
```

But I'm seeing a lot of alerts that seem like normal behavior for my test accounts. I keep hearing about Lacework as a more "context-aware" platform.

For those who have used both, does Lacework actually give you fewer false positives than native GuardDuty? I'm especially curious about things like S3 bucket scans or weird IAM calls from new regions. Is the difference big enough for a junior team to justify the extra tool?
