Royal Enfield GT650 (4 months old), Himalayan 450, KTM 390 Adventure X which one should I go for?

I’m a 28-year-old male (6’4”, 90 kg) and have been riding my Honda Trigger 150cc for the past decade. Now, I’m looking for an upgrade and struggling to decide between a couple of options. A friend is selling his Royal Enfield GT 650 (alloy wheel variant) for ₹3.2 lakhs. I’ve seen him use it since he bought it, and it has barely clocked 2000 km. He’s selling it due to health reasons, so I know it’s in great condition. However, in the same price range, I could also get an adventure bike, which seems more suited to my height and offers better comfort for long rides. Given that I ride around 150-200 km per week as a daily commuter, I’m torn between the GT 650 (the higher CC numbers do matter to me, it's dumb I know) and an ADV bike, which might be more practical for my needs. How should I approach this decision? Would the GT 650 be a good daily commuter, or should I consider an adventure bike instead?
