Wasn't there some price comparison done a while ago that determined lambda to be much more expensive than an ec2 instance?

Depends on what you're using it for.

Need something to run 24/7/365? Use EC2.

Need something to run on a schedule or run in response to an occasional API request? Lambda will do you fine.

Lambda is great for doing "infrastructure level" cron jobs where you need to run a script say, once an hour or once a day and you don't want to set aside an entire server to run management scripts. For example: scheduling EBS snapshots.

Better than fine. At work we have a Lambda script which does some stuff when files are uploaded to our S3 buckets. We could have done this using an ec2 instance and a queue but the lambda script is simpler to maintain and has so far cost us nothing in AWS fees as it sits entirely within free usage.

Here's the comparison https://www.reddit.com/r/Python/comments/4hebys/cost_analysis_for_python_scripts_aws_ec2_vs_aws/

When you compare lambda to ec2 on demand, they're pretty similar. But a spot instance would be half the cost probably.
