My oldest brother can shoot in the low 70s right handed, and then play another 18 holes left handed and shoot in the high 70s, using crap rental clubs.
I've never beat him right or left handed.
Until you are better than your clubs you do not need better clubs.
But here's what I suggest: ask for advice and ignore all of it you don't like, instead patiently wait for someone to give you some advice you do like and go with that
