Do you prefer having multiple brokers or consolidating everything into one?

I have been considering consolidating my multiple brokerage accounts into just one (Fidelity) since all of my work offerings (401k and stock plans) are through them and was curious how you all handle this. Do you prefer multiple accounts? Do you prefer having everything with one broker? And what is your reasoning for it? Brokers pretty much have all the same offerings so it seems its more just a preference for what features each one offers.
