Both cities have a lot to offer. Is the business part of your trip in the city you will be staying in? That might make a difference convenience wise. Also depends on what area of each city you can choose from.
In Irving I would recommend the Las Colinas area. In Arlington the area around the Cowboys stadium or the Arlington Highlands area at Matlock North of I-20. You have your choice of all the chain hotels in both cities. Nothing really upscale in Arlington. Several upscale to choose from in Irving such as the Four Seasons, Omni Mandalay. If you stay in Arlington, the Cowboys Stadium tour is worth seeing. You're also 15 to 20 minutes away from downtown and the cultural district in Ft. Wroth. Lot's of things to see, do and eat.
Both are fairly easy to navigate and parking isn't a problem and is free in both cities.
