contender for what?Sound like a studio gateman who is so high in weed.They tend to block with your kind of madness.You have never seen Tanzanians and you have never even seen a good number of typical represanative of several classes to come up in you stupid conclusion.No wonder why so many Kenyans act stupidly abroad against TZ until they are outshined.Tanzania and kenya have similar people,with respective groups in various social achievements.Kikuyu ,Maasai, Jaluo, Taita and Coastal guys have got equivalent groups in TZ ,same tells much about characters,work patterns and contribution to the nation success.You will see less course hardworking groups are not doing popular things, successful business dont show their success because CCM would come against.You would never seen much in Moshi.But chaga have establishments even in Nairobi and are part of your pride here.You would blindly think its only Tanzanians who fear Kenyans but the opposite is also true.I know lots of TZ who are now use Kenyans land for agriculture than you can imagine. All the estate you listed here cant outweigh estates in Dar .I have recently passed in Kawe,Msasani, tegeta,mikocheni ,masaki, etc and i can tell you Dar has very nice residential house Nairobi cant match .Dar residential building are much spread and real estates have grown so quickly than you can imgine.Nairobi can only talk when its comes to hortculture,number of hotel birds ,roads for the moment and possibly arrangement of tall buildings.And these are very dynamic parameters.Its like the forbed List of Billionaires...today is Bill gates,tomorrow is Carlos Slim ,then you have Russians,then Indians in top ten etc. When this projets is about to be finnished another is starting and another is planning stage.Outside Arusha there is Dolly estate ,is quite another world in Arusha, not many people knows it or even have a clue despite recent advertisements.Its designed for really rich guys and would accomodate so many houses ,with private sports complex and clubs,already well advanced with polo clubs,golf and other sports and leisure clubs. residents are automatic members.World billionaires are already in ,I wonder if you poor kenyan can evaluate better than these guys.I have been there,only the richest of Kenyans visit for golf and polo competitions.
