Pros
The Headquarters has an onsite nurse, onsite gym and trainer, you're not generally micromanaged, and you feel like the managers, directors, and higher ups in the company do care about your well being and success. Great starting position and introduction into the reseller industry. If you are a senior Account Executive, or strategic account manager you make quite a lot of money,
Cons
Often times, as an agnostic reseller, you almost compete against your own colleagues and there are at times barriers to working together with other teams supporting different vendors (for example, you could be on the Dell team trying to work with the Microsoft team, but they won't work with you because you could take their customer). Also a lot of the work you do (at least as sales support) goes generally unnoticed, ignored, or unrecognized. the ceiling is very low and vertical growth in the same team is highly unlikely.
