I do think memorable domains are more valuable, but there is a certain coolness factor in having a nifty phone number. For my own purchase, I couldn't remember the new mobile phone number I was assigned recently (I got a 2nd number via eSIM for my dual SIM iPhone), as it was a horrible combo of digits (although it was in the 416 area code, at least). Browsing through NumberBarn, I found one that was an improvement for under CAD $200, so it was worth grabbing. I was able to buy it and port it to my cell phone provider (to replace the assigned mobile phone number) all within a week.
