Between the options you've shortlisted, we'd advise choosing between the TVS Ronin and the Royal Enfield Classic / Bullet 350 for their laidback yet neutral riding positions and thumpy, torquey engines, as well as comfortable suspension setups.
You should also look at the Honda CB350 models, as they have a similar feel and look to the Royal Enfield bikes, but have a more modern and lighter riding experience.
Take a test ride of every machine you're considering before making your purchase.
