When confronting players in a 1v1 you should do the no Right Thumbstick strafe, by this I mean keep your aim on their head but try not to give the thumbstick too much movement or none if possible so you can be super precise, this has always worked for me, jumping with that tactic is also decent. Another thing I noticed was that you're slightly sloppy with your reactions (No offence) but I think that's to do with the fact that your sensitivity was too low (You already mentioned this I know, go for a 4-6 sensitivity). Other than that you seem good with map control and things, good luck out there on the battlefield!
