[PubQ] US-based writers with UK agents, what has your experience been?

I am in a 2 week agent offer period and am in the unexpected position of choosing between an agency based in NYC and one based in London. Both are established, reputable agencies. I think I clicked with the UK agent a bit more on the call, and I still need to reach out to client references, but I was wondering if anyone based in the US could speak to their experience working with a UK agent? I know the US market is quite large compared to the UK so I want an agent with a strong sales history in the US regardless of where they are based, but beyond that am pretty ignorant of any obvious drawbacks (or perks) I might be overlooking?
