But you need to realize that just because you've been approached for acquisition and even if somebody tells you straight up "we want to acquire you", it sounds like you are far away from actually getting acquired. The road from casual interest to money in the bank is long and bumpy.
Unless you actually have a term-sheet in your inbox, you aren't in the position to make this decision right now.
The right tactical approach is for you to push hard on both fronts - push as hard as possible on fundraising as if you have no other option. And if you do want to consider an acquisition, start approach these companies and ask for term sheet.
If both go well, then you have a decision to make.. (and more leverage..)
