The kind of scope you buy depends on what you prefer, what you need it for and how much you can spend.
I like high magnification, but a friend of mine prefers 100 yards shots at 4x magnification (no jest).
For Field Target you would want tremendous magnification for rangefinding (50x), for medium range rabbit smacking perhaps only 6x, for dawn and dusk hunting perhaps a fixed power with a big objective for light gathering.
Some people save their money for a year and are very happy with a BSA scope, others are more wealthy (or addicted ) and want nothing less than a Leupold with gold filigree decoration.
Sorry for answering your question with a question, but without more input it is very hard to make any recommendation.
