Accountant or tax advisor,,,what do other Landlords use?

Other

Just asking [non financial type]Landlord colleagues if they have found the services of a tax advisor over those of an accountant more enlightening or usefully proactive.
Has anyone out there tried both and found a positive difference.I am at the cross road and thinking of which signpost to follow.

If you gleefully say that yours does both...don't expect me to smile back unless you can provide a contact no and it is in the Manchester area.
