Dolibar is ERP centric with some useful CRM-features. BUT it is not a CRM system.
For CRM you should look also into SugarCRM and their forks like Vtiger, YetiForce, coreBOS etc.
Whatever of your feature requests dominates your daily work will help you to decide.
There exist some good websites too, which offer compregensive comparisons. Otherwise you have to use your ow comparison table.
Best regards.
