Difference between python boto get_contents_to_filename and s3 cp?

I hope this helps you . aws s3 cp is using the Boto3/botocore library internally but written efficiently. From I/O perspective for large number of files, the CLI will be faster since I believe it handles buffered I/O efficiently than if you do using Boto3. I am not aware any benchmark/tests that compares the efficiency of these methods.

What's the difference between Amazon's official S3.py vs boto.s3

it should still fix some issue I suppose that, by S3.py, you are referring to the code available to download here. So, please correct me if I am wrong.
In this case, IMHO, boto has some advantages, as pointed out at the Getting Started with AWS and Python tutorial:

What role permissions are required to use get_contents_to_filename?

it should still fix some issue You have to give permission to the objects in the bucket, not just to the bucket. So your resource would have to be arn:aws:s3:::/*. That matches every object.
Unfortunately, that doesn't match the bucket itself. So you either need to give bucket related permissions to arn:aws:s3::: and object permissions to arn:aws:s3:::/*, or just give permissions to arn:aws:s3:::*. Though in that latter case, giving permissions to a bucket named fred would also give the same permissions to one named freddy.

Difference between s3cmd, boto and AWS CLI

Any of those help s3cmd and AWS CLI are both command line tools. They're well suited if you want to script your deployment through shell scripting (e.g. bash).
AWS CLI gives you simple file-copying abilities through the "s3" command, which should be enough to deploy a static website to an S3 bucket. It also has some small advantages such as being pre-installed on Amazon Linux, if that was where you were working from (it's also easily installable through pip).
code :
$ aws s3 sync . s3://mybucket

What is the difference between the AWS boto and boto3

To fix the issue you can do The boto package is the hand-coded Python library that has been around since 2006. It is very popular and is fully supported by AWS but because it is hand-coded and there are so many services available (with more appearing all the time) it is difficult to maintain.
So, boto3 is a new version of the boto library based on botocore. All of the low-level interfaces to AWS are driven from JSON service descriptions that are generated automatically from the canonical descriptions of the services. So, the interfaces are always correct and always up to date. There is a resource layer on top of the client-layer that provides a nicer, more Pythonic interface.
