The fact you're asking strangers on an internet forum is really quite telling. Neither are particularly nice and over-priced, the Aspinal one scandalously so! Also, I'd never buy a mock-croc bag like this either as they just look cheap and well, plasticky.
If you're after a shopper style tote, buy a Mansur Gavriel one - beautiful leather and a wide range of colours. Price more in line with the Aspinal one but a million times nicer. You should check out Smythson handbags too as their leathers are lovely too. All in all, if you're willing to spend £800 you can get something so much nicer!
