(1) Go to the monero website you cited.[0]

(2) The top merchant directory recommended was 'cryptwerk'. Follow that through

(3) Compare https://cryptwerk.com/pay-with/xmr/ to https://cryptwerk.com/pay-with/ltc/.

(4) Note there are 2x vendor for lower market cap LTC, 3x as many for higher market cap BTC. Note this directory was chosen by monero people themselves, so I'm not cherry picking something gaming the merchant list against monero.

There is a pretty consistent survey of XMR performing weaker than similar class assets in spending at crypto accepting vendors. (Note I had to reply above earlier because my account was throttled)
