Seriously, does anybody care about the style used on a website when making a payment?
Also, as a user, I'd rather see a single consistent style so I have some confirmation about what bank I'm dealing with.
Stakeholders tend to.
Style may have been a poor choice of wording, as I meant the workflow as well as aesthetics. Keeping the user on the site and having complete control of the checkout process can lead to better conversion rates and up-selling than throwing them to a payment provider and maybe getting them sent back.

Which is one of the reasons I listed to include PayPal, as the logo is well recognised.
