My opinion, both are good stock & got pro and con.

For Genting Malaysia,
Pro 1: Gaming industry always work, never consider sunset industry resulted by human nature greedy. The business always need innovation, special and unique. Example like only 1 casino in Malaysia.
Pro 2: Geographical diversification gaming industry in UK, US, Malaysia, Bahamas and Egypt is perfect.
Con : 50% revenue of Genting Malaysia business which rely on Genting Highland now still affect. Hopefully recover soon.

For Genting Berhad,
Pro 1: Conglomerate diversification in 7 major field namely gaming industry, plantation, property, oil & gas, power plant , bioscience and hotel resort.Multiple interest less risk in today pandemic condition.
Pro 2: As parent company, there will be higher growth for Genting. Example is Resort World Las Vegas & CELU which will listed soon.
Con: As holding company, the profit in theory came from subsidiary company dividend. This resulting lower dividend yield compare to Genm.

For Genting Berhad stock holders, each 1000 unit of Genting Berhad share represent
1) 756 unit of Genting Malaysia
2) 1634 unit Genting Singapore
3) 119 unit Genting plantation
Resort world Las Vegas, Genting Energy, Awana resort and Bioscience Division is an added value.
