If the adventure pack is play any race in any pact, then adventurer hands down. Still don't agree with one of the most popular TES races [Imperial] hid behind a paywall, but that's an entirely different conversation and is what it is.
Currently you can only play with members of your own faction, so if you find a guild you like and they are all one faction, it really sucks being locked down to just 3 choices of character.
If options weren't necessary, and everyone played the same way, no one would use addons. Fix the UI!
