Yes she definitely is.
She can dance (see Chasing Time video)
She can sing (See Luxury acapella)
She can freestyle (see yesterdays freestyles, old videos on youtube)
She writes her own lyrics (See all her songs)
She is very versatile (Compare songs like **** Up The Fun to Atlantis to Venus to Bambi to 1991)
She was the executive producer of her own album (See BWET)
She is one of the BEST live performers right now (See all the articles praising her Coachella performance)
She's critically acclaimed (See basically every critics reviews, check metacritic)
Besides her attitude (which I couldn't care less about because I'm not a piss baby that cries because someone dragged my fav) she is pretty much the whole package and no other rapper can come close to that.
