To be honest as a foreign visitor I would rather just pay a simple daily charge, that I understood. I am not going to want to navigate the complexities of the current contactless system in London particularly if English isnt my first language. No it wouldn't stop me visiting, but it is part of the overall 'impression' that you get of a tourist destination.
The Visitor Oyster card is designed for this purpose, though I do think it's odd that it comes with a "round" preloaded value on it and not multiples of £8.10 (Zone 1-2 cap which is applicable to most tourists - most don't head off to Croydon or something).
I think tourists are perfectly fine with stored-value cards, they're the only option in some places e.g. Istanbul.
