One big difference is lounge access. If you get your *G from UA or US, you cannot access the domestic lounges if you're on a domestic itinerary. On the other hand, if you get your *G from any other airline, you'll get lounge access all the time.
It's generally better to get status on the airline you'll fly the most because airlines give preference and perks to their own elites that they don't extend to other *G members (such as E+ on UA and some upgrade possibilities).
Most airlines require 50K to qualify for *G. However, it onmly takes 35K on AC BD is 38K. I believe TK is 40K to qualify and 30K to re-qualify.
