Not so simple.
To send out your traffic you still need to resolve your L2 information. If your desired egress interface is a broadcast media, like an ethernet link, then you need to resolve the L2 address of the next hop.
But who is the next hop? You have just specified the egress interface.
I think "set interface" works well on P2P, not so well on broadcast links! So specifically for Udo scenario I think the "set interface" it'll work, but I don't think the 2 commands are equivalent generally speaking.
Udo, lab it out and let us know your findinds!

Subject: Re: Policy Routing - What set command ?
Hi,
I don't think there is any other difference, except - when you use 'set
interface', the router will send the packet out through the specified
interface. And 'set ip next-hop x.x.x.x', the router has to do a lookup into
routing table for the next hop address x.x.x.x and send the packet.
