Using this answer as a guide, I wrote the following
// Load the AWS SDK for Node.js
var AWS = require('aws-sdk');
AWS.config.apiVersions = {
sesv1: '2010-12-01',
sesv2: '2019-09-27'
};
var sesv1 = new AWS.SES();
var sesv2 = new AWS.SESV2();
//list intance methods
console.log(Object.getOwnPropertyNames(Object.getPrototypeOf(sesv1))
.filter(m => 'function' === typeof sesv1[m]))
console.log(Object.getOwnPropertyNames(Object.getPrototypeOf(sesv2))
.filter(m => 'function' === typeof sesv2[m]))
ran this with node and YES, there are major differences:

I would suggest if you are dependent on a method that only exists in v1 to stick with using v1. If you find a method you have to use from v2, then you will have to build an instance of v2 and use it alongside the v1 object.
