The 190 does pull better throughout the rev range and the gear ratios are slightly different. IIRC the 140 sat nicely at 60mph in 6th around the 1500 rpm mark wheras the 190 was closer to 2000 rpm maybe just over.
Other than that pretty much the same car chassis, body, interior wise with a few extras but nothing you cannot retrofit. If you can stretch to a facelift T Sport you do get 17 inch alloys, spoiler and better leather interior as well as the darker dashboard. Again nothing you cannot retrofit if you wanted to.
