If the OP is a bochur in a yeshiva that davens sefard, then it makes a lot of sense to daven the way the Yeshiva is davening. My rebbe rav belsky almost never davened his actual nusach because Torah Vodaas davens sefard, and he was there his entire life.
Sefard as a whole is the product of an immense labor undertaken by the early chasidishe rebbes, especially the maggid.
