Most popular star systems mod?

[Lady Lucina]

If someone wants to expand the Kerbol system with mods, most people would go and recommend adding OPM or MPE. Those two (especially OPM) are basically the gold standard for when you want more planets but are unsure which of the packs to pick.

Is there something similar for adding new star systems as well? There are a number of mods that add new systems and I'm having trouble to decide, so I wonder if there is also a 'classic' that many people would recommend for expanding a modded career beyond the Kerbol system.

If you follow the directions in JNSQ you can have all 3 star systems all together, need interstellar capable engines or use wormholes... (I forget where it talked about wormholes between the 3 stars.)

NOTE: KSP 1...
283 mods
3 star systems JNZQ, Galileo, Grannus planet packs (Each planet pack uses about 3 GB. ram)
A lot of visual mods (parallax)
26 GB. ram used at the start menu.
29 GB. ram used at the KSC with a NEW sandbox game.

The ram usage will go up as I start putting things in orbit.
