Most useful elite diary?

Recently I completed the freminik elite diary which had been a long time goal of mine. I was mainly lining it up for those juicy noted dagannoth bones, like most people probably do. However once i completed the diary I realised how many useful things there are outside of those noted bones.

This is the only elite diary I have completed at the moment, and I think it is one of the most useful. what are your thoughts?

Which diary would you say is the most useful?

Lumbridge, no question! So much comes with completing it that'll you'll use for the rest of your rs career. Being able to use fairy rings without a staff, an extra block slot for Slayer tasks, and 30 free high alchs a day that you can use on any spellbook. More comes with it too but those are the points that really sold me on it

I have to echo @DabbingBrb on this one! Whilst I haven't actually achieved any of them myself yet, from reading all of the perks / rewards I think that Lumbridge hits the top spot purely because of the ability to use fairy rings without a lunar or dramen staff!

Second place I would say maybe goes to Karamja because of the teleport straight to Duradel and we all have a whoopsie once in a while and that extra fight caves life has come in clutch for many people I'm sure
