I guess we can conclude, that the photographic film industry has reached a level where bad film is not produced any more, especially by well known brands. Some films may be unsuitable for certain tasks or damaged by improper treatment (storage, exposure, processing), but generally they all work well. So if you get film from reputable sources, store it properly and take care when developing it, you shouldn't get weird color casts or other effects you so frequently read about. Once you've done some shots with some average film, you can still decide whether you'd like more or less contrast/pop/sensitivity and change to some more suitable film for your particular task.
