Tried a GRG170DX and loved the neck — which higher-end Ibanez feels similar?

Hi everyone, I’m not very familiar with Ibanez naming conventions, so I hope this question makes sense.

Yesterday I tried an entry-level Ibanez (GRG170DX), and I was honestly surprised by how comfortable it felt — especially the neck and fretboard. It felt very flat and easy to play, and I really connected with it.

I usually play higher-end guitars, so this caught me off guard.

What I’d like to understand is: which higher-end Ibanez models have a similar neck profile and fretboard feel (same kind of flat radius and overall ergonomics), but with better build quality and components?

I’m not necessarily looking for “the best Ibanez”, but specifically something that feels like that GRG, just at a higher level.

Any guidance would be really appreciated!
