There are 2 main reasons why many people prefer upright vacuums. Firstly the person operating the vacuum can stand in a more upright position, this in turn alleviates back strain. Please note though many upright vacuum cleaners are much heavier than cylinder vacuums & the user is always pushing the weight of the whole vacuum backwards & forwards rather than just the hose, tubes & floor tool. Something to consider. The second reason people prefer upright vacuums is that the beating action tends to revive the carpet pile giving the carpet a newer & fresher appearance.
