I bought an iPhone X 100% based on the Qualcomm modem. I have the Apple store CDMA qualcomm version even tho I'm on T-mobile which had the intel version available sooner and cheaper. T-mobile service in San Francisco is absolutely terrible. Doesn't work deep inside most buildings. In the past I went through a bunch of iPhone 7's on T-mobile due to loss/theft/damage. Also compared many side by side. Some with qualcomm, some with intel, always on T-mo. Signal was a little better with qualcomm, battery life was SIGNIFICANTLY better with qualcomm. I'd guess 20-25% which is the difference between the phone dying by the end of the day or not.
