Seems like a non-issue. Whipping cream by hand takes less than ten minutes and it's quite good. It's not going to be as fluffy and light as the stuff with nitrous oxide, but for topping I think that's not the point.
From a can it's always UHT so tastes, for want of a better word, industrial. Though I'd just call it horrible and would be offended if served it. Let's be clear, no one is going to mistake it for real cream.
Real whipping cream and a couple of mins with balloon whisk is the only way to go.
Honestly I prefer the nitrous whipped creams, hand-whipped heavy/whipping cream is second for me. Alex seems to think that flavour is universal, and that all the people who like other flavours than him are plants from the food and beverage industry.
