【Get】 ,  【obtain】 ,  【procure】 ,  【secure】 ,  【acquire】 ,  【gain】 ,  【win】  are comparable and often interchangeable when they mean to come into possession of.

【Get】  is very general in its meaning and simple and familiar in its use. Thus, one may  【get】 something by fetching, by extracting, by receiving, or as a return.

【Obtain】 is likewise rather general. It may suggest that the thing sought has been long desired or that it has come into possession only after the expenditure of considerable effort or the lapse of considerable time.

【Procure】 is likely to suggest planning and contriving over a period of time and the use of unspecified or sometimes questionable means.

【Secure】 may suggest safe lasting possession or control or it may suggest the gaining of what is hard to come by (as by reason of rarity or competition for possession); thus, one secures, rather than gets or acquires, a rare stamp by offering a higher price than other interested persons will pay.

【Acquire】 may suggest devious acquisition. It may also indicate continued, sustained, or cumulative acquisition.

【Gain】 often implies competition in acquiring something of value.

【Win】 , though often interchangeable with  【gain】 , may suggest, as  【gain】 does not, favorable qualities leading naturally to the acquisition of something desired despite competition or obstacles.
