This is a great comparison and while you might not be seeing tipping services on InLeo (although some OGs are offering free valuable insight), I believe that the Premium Subscription from here is well worth it. I am paying for it on a monthly basis, but I am thinking to switch to an Yearly one as it makes life easier and also I think you get a discount. And the perks are invaluable or some of them even well valuable compared to the payment for it. ;)
