It’s not possible to give a correct answer that will be right for every single scenario and for every single shareholder. For example, if the management is bad and it destroys value, a takeover can be good. On the other hand, if the acquiring company buys a company, transfer some assets and liquidate the assets, this scenario can be a bit trickier.
Control and dilution of control is also quite relevant. For example, what are the holdings pre and post the takeover look like? This is very important since it can determine the operations of a company as well as the dividends and other quite significant decisions.
