We use both Twilio and Plivo in our text messaging products in CallHub. Both are great vendors to work with. We'll not move to Amazon just for a lower price. The things that we value are,

1. Quality of delivery

2. A consistent API across all our telephony needs.

3. Great support when we need it

I especially love the fact that these vendors are constantly innovating and give us early access to those innovations as well. The most recent was Twilio's release of studio.

CallHub probably has more demanding requirements for a call and SMS platform than most customers. If I understand your business correctly you provide robo-calling (!) services for political parties. Most companies use Twilio in very basic ways.

In terms of innovation in SMS and telephony, there are also numerous ways you can see Amazon surpassing Twilio. For example, combining speech detection, automation, etc. from Alexa with their platform.
