Should I take a counter offer from my company?

I recently was contacted by a different company for an interview and they extended an offer for a new job. This job has decent benefits, but its with a smaller company than i am with at the moment. The offer would give me a pretty big raise from what I am at right now. There has been talk that the new company has a possibility of closing or being bought out in the near future.

The reasons I have entertained this offer is for two reasons, one being what I am being paid now and the feeling that I can earn more. Two, there is currently a disruptive co-worker who works beside me and has made the job feel stressful every day I come in.

After I discussed that I have an offer from a different company, obviously my current company decided to make me a counter offer. Their counter, will give me a higher pay than what I would get at the new company and more vacation time than what I would get at the new company. On top of that, there have been multiple HR complaints about this one employee and they are correcting the situation by moving her to a different area in the office away from people. On top of that my current company has told me the plan for moving me into a manager type role in the near future.

Ultimately, I plan on leaving the field I currently am in, in about 2 years. So would taking the offer be worth it especially if I get management experience along with it? Or should I take the offer from the new company and start from the bottom?
