Ought to I exploit Electrum Pockets OR Bitcoin Core as my web site’s fee gateway?

I am a developer who’s constructing an internet site that must course of Bitcoin fee requests. So I would like a fee gateway.

In my final challenge, I used Electrum pockets as fee gateway however my final challenge would not have an excessive amount of bitcoin fee requests, and electrum works wonderful.
However I am afraid of electrum’s limitations and I am unsure it is a good suggestion to make use of electrum when processing numerous fee requests.

Bitcoin Core runs bitcoin node but it surely takes an excessive amount of disk area (full node) or CPU utilization (prune mode) and I am afraid it is not a good suggestion too.

So please inform me which one preforms higher as an internet site’s fee gateway, and why. Thanks all for answering.
