The TX9000 is using a newer CTS firmware 1.9 which does achieve up to 20% savings in bandwidth so 10Mbps is feasible. The challenge with your question is that video is inherently bursty based on a ton of variables, motion being a big one. Cisco is giving an average/typical figure at 10Mbps and your Cisco partner is playing it safe at 14Mbps. You have to decide which case you want to engineer your network for: typical or worst. For the cost of this equipment worst case seems like the logical choice. Also don't forget about things such as content sharing which also consume bandwidth.
This answer really depends on the Main Video resolution and Frame rate you are setting the TX9xxx to for the CUCM Device profile "Product Specific Configuration Layout" for the : Quality (per Display) as well as Main Display Frames Per Second and Bandwidth Allocation Weights all play into this factor.
