Ownership of a freehold - what's the best form?

I wonder if anyone has advice on this issue: my neighbours and I are planning to buy the freehold of our flats on the Ladder (the usual set up of two flats in one house). We have negotiated a reasonable premium with the freeholder and are ready to proceed. But we're not sure what the best form of ownership of the freehold might be. Some online advice suggests setting up a company and some suggests owning it as tenants in common. We asked our solicitor and she basically said 'it's up to you' (!).

What have other people in the same situation gone for - company or tenants in common? What pros and cons did you experience?

Any advice gratefully received. Thank you.
