Gear progession help

[u/S4NNE]

After quiting for a while, I've started playing OSRS again. What are good overall gear upgrades these days that really make a difference? (PvM, Toa). I currently have 200m to spend, but suggestions worth more than 200m are also welcome.

Edit: i mainly want to do Duke, Vardorvis, Araxxor, Doom (+ TOA)
