Buying elixer with gems?

Is there a bonus/discount/advantage to buying elixer or gold with gems as opposed to using gems to pay for an upgrade?

I plan to use gems to speed up a few upgrades I started before my th8 upgrade finishes. But if I decide to pay for upgrades is it better to fill my storage or to may for the upgrade directly?

Truthfully I would save my gems for builder huts

I have 3 I guess I can buy the 4th and still have enough to speed up a few upgrades.

But the question is do I save gems by buying gold and using it to upgrade or just using the button to finish an upgrade? Does it make a difference in the gem to gold exchange rate?

And now I have 4 builders... I can fast forward one upgrade tonight before bed and start upgrading 2 more things. Probably the spell factory so that I can get the next spell unlocked.

Huh i dont have much experience gemming building since I just save mine for builder huts

Much better off boosting your barracks and farming instead

Meant that spell factory will be the last upgrade before th8 upgrade finishes. My next upgrade will be my teslas or archers. Already upgrading my primary mortar.

I am losing my mind... I was confusing 2 different questions.

Yes, I farm all day but I want to get a few upgrades completed before my th8 upgrades finishes in 2 days. Already lost to attacks (needed the shield anyway but it cost me 300k gold and 200k elixer!)

Sorry my friend but I'm not following ya

Edited original post. It was so confusing and I haven't even had anything to drink!
