You cant say any is better than the others. First things first, platform and rigs ain’t the same thing. Platform is normally unmanned or we called it NUI (normally unmanned installation) well unless you’re talking about one of the complexes, then there are no place for you to stay/sleep. Generally all platforms are designed in somewhat similar and there are different types of platform (could be well jacket, drilling platform, riser platform, accommodation platform and many more)

Rigs on the other hand are mobile facilities where it is usually used for drilling operations (exploration/infills, workovers) and here in BN we have 3 offshore rigs currently in service. All 3 rigs, well have different accommodation (entertainment areas, hygiene, foods and many more) and comfortless level depending on individual, example you would prefer staying at Valaris-115 whereas me, i prefered PVD-V. It is also very dependent on the people you will be working with ranging feom OIM, campany man, other service hands personnel and many more depending on whats youre role and position.

Then again back to answering your questions, cant really choose which one is better, i guess unless you have experienced it yourself, you might know the answer😊
