Can't say about HMC as neither work nor been there and would try not to be there (touch wood). For living, if you are from USA then the importance you would get here in Qatar may not be so in Abu Dhabi but life in AD is much better than Qatar (except for finding parking places). Life is more vibrant, with Dubai next door, in AD. Basically one feels alive in AD, here for last 4 years I feel I have been dead all this while. Just MPO as a single Indian.
