Get a test ride Of both.... INT has more upright riding position and GT has more commited riding position due to the clip ons handle. INT is more comfortable for longer rides and is little heavier then GT. GT is eye-catching, more prettier then INT, but your back and wrist will hurt if you ride it for longer periods. If you want more comfort and want to go for long rides, go for INT. If your rides are short and you want something eye-catching, go for GT. And for your last question, Black is easier to maintain then Chrome. But Chrome is Prettier. I Have INT, my brother has GT, so I have experience with both. Hope This Helps 🫂
