Your learning curve will not be steep, as Gig Performer uses the visual approach, the documentation is always up-to-date with new Gig Performer updates (or major upgrades), and there are many Gig Performer gurus that are active here (a beer for them 
).
On top of that, developers are also active in the community, so Gig Performer is really a “no brainer” choice 
P.S.
We have the Helix Native prepared gig file, with some goodies, downloadable for free: [Gig] Line6 Helix Native - 8 Snapshots
