I honestly think this depends on which gods you have and who you are against for me the main goal is to get the mid to lane before the enemy mid laner if the mid lane is behind that means there pushed under tower to clear sometimes using a health pot and are in a worse position to contest mid harpies which means enemy jungle and mid get level 5 first etc . Im sure in many ways it ' s probably worth it but in casuals where top picks arnt always picked and not everyone starts with back harpies I find it puts you further behind than ahead if everyone did it like in SPL it would be better because it would slow everyone getting to lane but the fact only a small handful of people do it means 2 lanes are late to lane and normally end up taking some creep damage
