For starters, pricing vs reserving is a different dimension than reinsurance vs insurance vs consulting. There are pricing and reserving reinsurance actuaries.
To that end, if you’re just a few years in I don’t think it makes a huge difference, can switch pretty easily (although recruiters will act like you’re a woman running out of time to have kids). Many will also recommend you at least want a mix of reserving and pricing experience based on the view of an ideal chief actuary, although I’ve been pretty happy to purely focus on pricing.
