If you convert to Developer Edition (3.22.1540.1), you will have 4.3 and Sense 5, but 4.4 with Sense 5.5 will be released as an OTA update in a few days. I'm sure OP knows better than to use superCID. It will prevent you from receiving OTA updates. Always use the proper CID for the firmware you're using (unless it's a custom ROM or something that you wouldn't want to do an OTA on). If you convert to the International version (3.62.401.1), you will have 4.3 with Sense 5.5, but be waiting until January for the Android 4.4 update. There's no real difference between the two. They're both world-wide variants, but the Developer Edition gets updated well before any others.
For Dev Edition, change CID to BS_US001
For International, change CID to HTC__001
For Dev Edition, MID must be PN712000
For International, MID must be PN710000
To flash from GPE, you may need to downgrade your Bootloader first. It was a nightmare for me getting off of GPE until I figured that part out. I assume you're already S-Off. Sneakyghost provided 1.44 bootloader can be downloaded here http://d-h.st/qfc
