I feel that the Oyster bracelet is more sturdy, and if your wrist expands during a hot day, if you do not have any 5mm extension or a glidelock feature, may feel a bit tight. But I like the feel of it.
Jubilee - I like the look - certainly more "Atas" - but if the watch head is heavy, may tend to drop off-center if worn a little loose. Suitable for DJ like glove in hand for sure! For GMT Master II - who cares - I'd still wear it any day! HAha
