If straight-line speed is your priority, the 390 Duke takes the lead. With 3 HP more than the MT-03, it offers a more spirited ride that will be noticeable on highway overtakes or track days. Both bikes share a similar footprint on the scale, with only a negligible 4kg difference between them, so handling characteristics will depend more on center-of-gravity than raw weight. Riders with a shorter inseam should lean towards the MT-03. Its seat height is 40mm lower than the 390 Duke, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: It's a close call. Choose the 390duke if you prefer its specific styling and ergonomics, or the mt03 if you want the alternative brand character.
