Personal experience of working with a few other providers recently is that @postmarkapp definitely seems to have the upper hand on speed.

Love the fact @postmarkapp are publicly sharing their status and deliverability details.

For outgoing transactional mail I strongly recommend Postmark. Had bad experience @ Mailgun and SendGrid with delivery.

Currently switching over all my transactional email to @postmarkapp. Great experience so far – awesome job, guys!

Two months since I switched from @SendGrid to @postmarkapp and deliverability/time to inbox has been significantly better. Plus, Postmark's support team is fantastic! Highly recommend using @postmarkapp for your transactional emails.

Okay @postmarkapp is amazing. Why has no one told me about this? Good riddance to all their competitors I've put up with for too long.

Postmark blows every other transactional email product out of the water.

Wow, even after two years of using Postmark I’m still surprised by how much you value your customers!
Wow, @gmail deliveries via @postmarkapp is really fast, ~1s! Seems to have an excellent #ISP reputation. #transactional #mails #service
