[2020] I want to swap to osrs, should I go for Ironman or Regular?

Hello, Im an rs3 player and for years Ive been watching osrs content on youtube, I always loved osrs and wanted to play it again, but was afraid of starting anew and grind so much again. But today I kind of felt like trying it out and I cant decide whenever I should go for an ironman or regular mode. My rs3 account is regular, so trying out ironman seems interesting with the idea of getting everything by yourself. Is it that much more time consuming or its not that horrible? I preferably want to pvm majority of my time, so my end game goal is bossing. So my question regarding time mostly revolves within whats required for bossing, food, gear, prayer, etc... how more time consuming is it?
