Is MPLS outdated?

I saw some providers called MPLS as a "legacy network". I know T1 is a legacy but is MPLS really outdated? If not MPLS, what do you suggest?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

No. It's not outdated.  

I'm guessing this provider has a different service that they are trying to push customers into.

The provider said:

SD-WAN is an option that dramatically simplifies the WAN by delivering virtualized services from the cloud to branch offices and mobile users everywhere. Leverage enterprise-grade performance, visibility and control over both Internet and private networks, combining the economy of the Internet with the flexibility of the cloud.

Is SD-WAN better than MPLS? in what ways?

I'm going to make an assumption that you're familiar with LAN switches, VLAN's, etc.  If you're not, I'll try a different analogy.

SD-WAN is to MPLS as SDN (or ACI if you're a Cisco person) is to the LANs we've been using all along.

The software defined networking thing may become the only way we do networks in the future. But for now, it's an exception rather than the rule.

If a provider offers both, I would tell them I'm not interested at this time. If they say that's the only thing they offer, I would find another provider.  

That said, if they are offering you a deal to be their guinea pig, and you think it's worth it, then go for it. I helped a consulting customer back in the 90's move from leased lines to Frame-Relay when AT&T made them an offer they couldn't refuse. Their WAN costs dropped to about 20% of what they were paying for 56k leased lines.
