Let technology work for you, new technology scopes have 5,6,7,8 and even 10x magnification ranges. They offer wide fields of view and also allow a precise shot at long range or small targets.
IMO 3x18x50mm is what I would chose if I had to pick only one to go anywhere with.
Not sure what your budget is but take a look at the Meopta Optika 6, and I strongly recommend second focal plane.
Do yourself a huge favor and pick out some options and then compare specs like FOV, magnification, Illuminated, etc. and warranty. Settle on that and find something in your budget and enjoy!
