It’s much the same style as George Town, yes! Hope you can get to Ushuaia one day - I was living in Bs As at the time so had no excuse not to get down there - and it’s absolutely worth it.
I really liked your comparison of Scarborough and Koh Samui. As a northern Brit now living in Malaysia I could make a similar comparison and I totally concur with your highly scientific conclusion :)
See you around!
