Agreed.
It must be because Electrum is widely recommended (for on-chain) and read somewhere that it supports lightning.

Personally, I've used it and I'm pretty much pro-Electrum
But I do not recommend its Lightning feature to newbies unless the person is really interested or insisting.
I just give them thorough explanation of the steps and the necessary "management" of the channel(s) and its liquidity.
This usually causes second-thoughts on using Electrum's lightning, at least, they are now well-informed of what they're trying to get into.

Then its up to them to decide to proceed to not.

I don't have other recommendations though.
