Cutting Mats, recommendations

Using glass would run the predicament of dulling blades down faster though

You're right, it does dull blades faster. However, they're easy to re-sharpen and some cuts are better done on an ungiving (solid) surface. Another benefit is that glass is impervious to paints, glues, and solvents.
The best choice is probably to use both a cutting mat and a sheet of glass, and use the one best suited to each particular task.
