PSU, VT, and UMBC are all solid engineering programs. Don’t focus on the rankings, because unless the difference is huge the actual impact on your career will be minimal.
That having been said, going to a branch campus WILL impact your experience - the smaller campuses for PSU and UM will offer an equally solid “base” engineering education but will not offer as many opportunities to really excel. Even if you wind up at the main campus, there will still be at least a small impact. What that means for you personally depends a lot on your ambitions, so consider what your long-term goals are and whether or not you can accomplish them from a branch campus.
At the same time, you will tend to do better at a school where you are more comfortable - for some people, a LOT better. It sounds like UM is not something you are really looking forward to, lacking both the opportunities of VT or the feel of PSU, so the question becomes which is more important to you - graduating with a solid degree from a more comfortable university, or having the better academic prospects of a “main campus” spot at a school where you are less at ease.
No one can answer that but you.
