Transaction test between wallets : BTC Vs. BCH Vs. LTC

Just did a little test between my wallets. I sent 90 dollars worth of bitcoin, 5 dollars worth of BCH and 5 dollars worth of LTC.

Bitcoin cost $1.90(0.00002816 BTC) (used recommended fee) to send and took roughly 15 minutes to show up in my other wallet. The sending wallet had a notification that the transaction failed for some reason, but ultimately went through. Weird.

Bitcoin cash cost $0.004 cents (0.00000678 BCH). The BCH showed up in my receiving wallet instantly, due to the zero confirmation feature, I believe. Then took around 15 minutes to finalize.

Litecoin cost $0.00014 (0.00000141 LTC) to send and showed up instantly in the receiving wallet and took around 7 minutes to finalize.

So, BCH cost 1/4 the amount of sats as BTC, but had the added benefit of showing up in the receiving wallet instantly.

LTC cost 1/20th LTC compared to BTC (tougher comparison since there are 4x the number of LTC as BTC).

I noticed I could not adjust the fees with BCH and LTC with the wallet I was using. Is this typical of all wallets?

Also, will the going rate for a BCH transaction always be a 1/4 the amount of sats as BTC. If not, can someone explain why that's not the case? I'm guessing it is not always proportional depending on congestion.

Just a fun experiment I did. Any thoughts and input would be appreciated.
