An in-house team gives you long-term retention of knowledge. The people internalise your domain over months and years, and that knowledge remains inside the enterprise angular development company. The price is slow hiring and fixed overhead: filling a senior role is slow, onboarding adds more time, and the salary carries on whether the roadmap is full or empty.
Project outsourcing implies an external team owns the outcome: the provider staffs the team, the provider manages the day-to-day work, and they absorb the staffing risk. The model works when the work is a defined project and you have a decision maker with time for it. It works badly when nobody on your side owns the product, since an external team cannot fill that gap for you.
Hiring individual contractors sits between the two: you add engineers while keeping the management yourself. It moves quickly — the right specialist can join far sooner than a new hire — and it scales down as easily as it scales up. The condition is that your own leads must have the bandwidth to manage them. Without that, you are paying hourly for uncoordinated work.

Last: cost comparison nearshore vs offshore development who owns it once the vendor leaves? Answer those honestly and the appropriate option usually chooses itself.
