black widow vs spiderwoman

Both have shield and avengers training. Black widow has additional KGB training while spider woman has additional hydra training. Black widow has her"widows bite"  and some spy gadgets. If the current versions of both fought in an office building(after hours) who do you think would win? Why? and How? 

Black Widow's quick regeneration and extensive training is the deciding factor

if you ask me black widow has more experience in combat but overall spider woman would overpower her

Spider woman has more pure power.

Widows gadgets may be the deciding factor here, otherwise jessica takes this due to strengh

Spiderwoman

Spider-Woman

Jessica.
